Introduction
Welcome toHTML and JavaScript for Visual Learners. If you’ve never
useda Visibookbefore,you’ll findthat it contains several hundred
illustrations,withcomparativelylittle text. It presents essential tasks,
breaks themdown intosteps,then walks you throughthemwith
illustrations.
What you’ll learn
You’ll learn howtouse HTMLtocreate a
solid,attractive Website that’s easyto
navigate. You’ll alsolearn howtoupload
it toa Webserver.
You won’t become an expert in Web
publishing—that takes practice andreal-
worldexperience. But you will learn the
fundamentals of site-building,andget a
goodfoundation on whichtobuild
professional-level skills.
Additional resources for acquiring expert-
level HTMLandJavaScript skills are
foundat the endof this book.
How you’ll learn it
This bookhas five sections: HTMLBasics,
Layout & Navigation,Interactivity,
AdvancedLayout,andPractical
JavaScript.
At the endof eachtaskandsection are
practice exercises. Don’t worryif you
can’t workthroughthe whole bookin a
dayor two. Take your time,andtrytodothe practice. You can check
your workagainst examples postedon the Web.
Follow thesteps

Before you begin
Before you begin,it’s important that you knowWindows well. A
working knowledge of Windows makes it mucheasier tolearn HTML
andJavaScript. You shouldbe familiar with:
• Howdirectories work
• Windows Explorer
• Basic wordprocessing
Make sure you can performthe following tasks:
• Create a folder on your computer’s harddrive
• Create a folder within a folder
• Copya paragraphfromone document andpaste it intoanother.
If you have trouble doing this,set
aside a couple of hours tolearn
Windows basics. Have a friendor
co-worker whois proficient with
computers walkyou through
Windows Explorer,creating folders
andbecoming familiar withfile
extensions.
You shouldalsopractice using the
Cut,Copy,andPaste commands in
a standardwordprocessing
program. When you can dothese
things on your own,you’re readyto
learn HTMLandJavaScript.

HTML Basics
In this section, you’ll learn how to:
• Create a home page
• Format text
• Create links to new pages
• Create e-mail and external links
• Insert graphics
• Create a navigation system
• Change page and link colors
You’ll build a site that looks like this:

4
Create a home page
Create the home page
1. Open a browser,suchas Internet Explorer or Netscape Navigator.
2. Open the programNotepad. Dothis byfirst clicking the
button on the taskbar,then Programs,then Accessories,then
Notepad.
3. At the topof the Notepadscreen,type:
<HTML>
Tip:HTML is a tag. Tags are instructions to a Web browser. This
particular instruction lets the Web browser know that what follows is
a Web page, written in HTML.
Tags can be written in upper-case or lower-case letters—it doesn’t
matter which. HTML, html, or HtMl are all fine.

5
4. Save the file.
5. When the Save As windowappears,select the C: drive in the
Save in drop-down list.
6. Create a newfolder byclicking on the icon.

6
7. Name the newfolder “Dogs,” then double-clickit soit appears in
the Save in box.
8. In the File name textbox,type index.html.
9. In the Save as type drop-down list,select All Files. When you’re
done,the windowshouldlooklike this:

7
10.Save the page byclicking on the Save button.
11. Belowthe HTML tag,type:
HEAD
!--Created by Your Name--
/HEAD
Tip: The HEAD section contains information that doesn’t show up
on the page when it is viewed in a browser. Note the closing
/HEAD tag: in HTML, you must give the browser instructions to
end something as well as start it.
Home page file names
All Webpages have a .html extension (or .htm).
All home pages have the file name index.html. index.html
comes up automaticallywhen the address of a domain or
directorywhere it’s locatedis typedintoa browser.
For instance,if you gotowww.visibooks.com,the home page
appears automatically. That’s because its file name is
index.html. If the file name of the Visibooks home page was
homepage.html,you’dhave totype
www.visibooks.com/homepage.html toget it toappear.
The Microsoft exception: Toget your home page tocome up
automaticallyon a Webserver running Microsoft’s Internet
Information Server as it’s operating system,give your home
page the file name default.htm.

8
Tip: !--Created by Your Name-- is called a comment.
Whatever text is between the dashes won’t show up on a browser’s
screen—it’s only visible if someone views the page’s HTML code. You
need to include the ! for this to work.
12.Belowthe /HEAD tag,title the page “AHome Page About
Dogs” byusing TITLE tags:
TITLE
A Home Page About Dogs
/TITLE
Tip: Note that the text “AHome Page About Dogs” is not a tag. It is
text surrounded by tags. The TITLE tags tell the browser what to
do with the text: make it the title of the page.

9
13.Belowthe /TITLE tag,add:
BODY
/BODY
Tip: Anything you want to be visible in a browser’s main window,
put between the BODY and /BODY tags.
Page titles
The title of a Webpage describes the page. It’s what appears in
a browser’s Historylist. The title alsoshows upas a linkwhen a
page comes upin a searchengine. If all your pages have
discrete,descriptive titles,they’ll be easier for people tofind.
The page title shows upin the top,or “title,” bar of the browser
usedtoviewit. The title of this page is Dogs.

10
14.Belowthe /BODY tag,close the /HTML tag. When you’re
finished,the code shouldlooklike this:
15.Between the BODY and/BODY tags,type the words:
Dogs Home Page
16. Save the page.

11
View the page in a browser
1. Gotothe browser andon its menu bar,clickFile,then Open.
Tip: If you’re using Netscape Communicator instead of Internet
Explorer, click Open Page,then Choose File.
2. When the Open windowappears,clickthe Browse button.

12
3. When the newwindowappears,navigate tothe Dogs folder in the
Look in drop-down list,then select the home page: index.html.
4. Clickthe Open button,then the OK button. The page should
come upin the browser andlooklike this:
You have createda home page titled“A Home Page About
Dogs.”
The home page’s file name is index.html.
It is locatedin a folder calledDogs on the C: drive.

13
Practice: Create a home page
A. What is the correct file name for a home page?
B. Why is there a special file name for home pages?
C. Why is it important that the home page—and all other pages in a
Web site—have accurate titles?
D. What is the difference between a page’s title and its file name?
Answers
A. index.html
B. It allows home pages to appear in a browser without typing the file name as part of a Web address.
C. Accurate titles allow people to find pages easier when bookmarking them or searching in a browser’s History list.
D. A page title appears in the Title bar at the top of the browser. It’s plain text, such as “The Smith Family: Vacation
Pictures,” that makes it easy for people to keep track of a page. A page’s file name, such as vacpics.html, is how the
computer keeps track of it.

14
Format pages and text
Change fonts
1. In front of the words “Dogs Home Page,” insert a FONT tag
withthe attribute FACE=”arial”:
FONT FACE=”arial”Dogs Home Page/FONT
2. After the words,close the FONT tag:
FONT FACE=”arial”Dogs Home Page/FONT
Tip:Think of an attribute as a sub-instruction to the browser. In this
case, the FONT tag tells the browser that text will be changed, and
the FACE attribute tells it how to change, specifying the Arial
typeface.

15
3. Viewthe page in the browser. Clickthe browser’s Refresh button,
andthe page shouldlooklike this:
Tip: If a page doesn’t look like it’s supposed to—or nothing shows up
at all—check the HTML code you’ve written. You might have left out
a quote or made some other small mistake. Something that seems
insignificant can wreck a page:
FONT FACE=”arial
Web fonts
When text is viewedon a computer,onlyfonts installedon the
computer can be seen. For instance,if someone createda page
that specifiedthe Tekton font,almost noone viewing it would
see it in Tekton because veryfewcomputers have that font
installed. Computers without Tekton woulddisplaytext in the
default font: Times New Roman.
All Windows computers have the Arial font installed.
Windows 95 andlater computers have Verdana. Macintoshes
have Helvetica,the font that Arial is basedupon.
Tocover all bases,specifymultiple fonts:
FONT FACE=”verdana,arial,helvetica”
Missing endquote(“)
Textis inthe
Arial font

16
Change text size
1. In Notepad,addthe SIZE=”+4” attribute tothe FONT tag:
FONT FACE=”arial” SIZE=”+4”Dogs Home
Page/FONT
2. Save the page andviewit in the browser. It shouldlooklike this:

17
Change text weight
1. In Notepad,addthe B tag in front of the words “Dogs Home
Page” andclose it after them:
FONT FACE=”arial” SIZE=”+4”BDogs Home
Page/B/FONT
Tip: Wheninserting multiple tags, arrange them in mirror-image
order. The tags and text above are a good example: since it starts with
the FONT tag, it ends with the /FONT tag. Tags that aren’t
arranged in mirror-image order can cause display problems in some
browsers.

18
Change text color
1. In the FONT tag,addthe attribute COLOR=”red”:
FONT FACE=”arial” SIZE=”+4” COLOR=”red”
2. Save the page. Viewit in the browser,andthe text shouldshowup
red.
3. Change the text color toblack,then save the page.
FONT FACE=”arial” SIZE=”+4” COLOR=”black”

19
Align text
1. Beneaththe present text andtags,insert a P tag tobegin a new
paragraph.
2. Beneaththe P tag,insert the tag FONT FACE=”arial”
SIZE=”-1” andthe words “These are my favorite
breeds of dog:”
3. Within the P tag,addthe attribute ALIGN=”right”:
P ALIGN=”right”
4. Adda closing /P tag after the newparagraph.
P ALIGN=”right”
FONT FACE=”arial” SIZE=”-1”These are my
favorite breeds of dog:
/P

20
Tip: Usually a P tag requires no closing /P tag in HTML, but
in this case the ALIGN=”right” attribute is used. The closing
/P tag after the paragraph keeps the browser from right-aligning
whatever is beneath it.
5. Save the page,then viewit in the browser. It shouldlooklike this:
6. Remove the ALIGN=”right” attribute fromthe P tag.
Tip: To generate a single-line break rather than the double-space a
P tag generates, use the BR tag. Putting a BR or “Break” tag
between two lines of text will bump the second line down to the next
line:
FONT FACE=”arial” SIZE=”+4”BDogs Home
Page/B/FONT
BR
FONT FACE=”arial” SIZE=”-1”These are my
favorite breeds of dog:

21
Indent text
1. Belowthe text,“These are myfavorite breeds of dog:,” insert three
newparagraphs:
PChesapeake Bay Retriever/P
PGerman Shepherd/P
PYorkshire Terrier/P
2. Enclose these paragraphs in UnorderedList tags toindent them:
UL
PChesapeake Bay Retriever/P
PGerman Shepherd/P
PYorkshire Terrier/P
/UL

22
Tip: Notice how all the text below the FONT FACE=”arial”
SIZE=”-1” tag looks the same. It will stay that way until the
closing /FONT tag is inserted.

23
Create lists
1. Withthe three breeds of dog,replace the P and/P tags with
LI tags togenerate bullets in front of the text that follows:
UL
LIChesapeake Bay Retriever
LIGerman Shepherd
LIYorkshire Terrier
/UL

24
Practice: Format pages and text
A. Why are the most common font choices Arial, Verdana, and
Helvetica?
B. What kinds of computers have the font Arial installed? Which have
Helvetica instead?
1. Change the title of the home page to“My Favorite Dogs.”
2. Change the bulletedlist toa numberedlist.
Tip: Use OL instead of UL to generate a numbered list.
3. Change the numberedlist backtoa bulletedlist.
4. Make the list items bold. When you viewit in the browser,the page
shouldlooklike this:
Answers
A. Those are the fonts that most Windows computers have installed.
B. Windows computers have Arial, Macs have Helvetica.

25
Create links to new pages
Step 1: Create a new page
1. In Notepad,change the title of the page to“Chesapeake Bay
Retrievers,” then take out all the tags andtext between the
BODY and/BODY tags.
2. On the menu bar,clickFile,then Save As.
3. Save the newpage withthe file name chesapeake.html.
Tip: Remember to Save as type: All Files.

26
4. Beneaththe BODY tag,type “Chesapeake BayRetrievers.” This is
the page heading. Make it verdana,bold,size +3:
BODY
FONT FACE=”verdana” SIZE=”+3”BChesapeake
Bay Retrievers/B/FONT
/BODY
File names for the Web
Most Webservers are Unix- or Linux-based,whichdon’t deal
cleanlywithspaces in file names. For instance if you name a
file fido page.html,it mayshowupin the URLbox of the
browser as fido%20page.html.
Also,Webservers are case-sensitive,sokeeping file names
lower-case eliminates a potential source of mistakes.
Make all file names in a Website—pages,graphics and
folders—lower-case,withnospaces.
Correct file name: german.html
Incorrect: German Shepherds.html

27
5. Save the page.
Providing navigation clues with text size
The heading of the Chesapeake BayRetriever page is made one
size smaller than the heading of the home page. That’s because
the CBRpage is one stepdown in the site hierarchy.
Level 1: Dogs
(toplevel heading; SIZE=”+4”)
Level 2: Chesapeake BayRetrievers
(second-level heading; SIZE=”+3”)
Making the heading of the CBRpage smaller than the home
page’s heading helps showpeople where theyare in the site.
Dogs
ChesapeakeBay
Retrievers

28
Step 2: Link to the new page
1. Open the home page (index.html) in Notepad. In front of the first
item,Chesapeake Bay Retriever,insert an anchor tag.
Then close the anchor tag :
LIBA HREF=”chesapeake.html”Chesapeake
Bay Retriever/A/B
How an anchor tag works
Anchor tags create a clickable linktoanother page.
A pagewith this filename… …is linkedtothesewords.
a href=”filename.html”New Page/a

29
2. Save the home page andviewit in the browser. The words
Chesapeake Bay Retriever shouldbe a link,andthe page
3. Click on the Chesapeake Bay Retriever link. The Chesapeake
BayRetriever page shouldappear in the browser.

30
Practice: Create links to new pages
A. Why should file names be lower-case and free of spaces?
B. Why should the headings on section pages (Chesapeake Bay
Retrievers, German Shepherds) be smaller than the heading of the
home page?
1. Create newpages for German Shepherds andYorkshire Terriers.
Page Title File Name
German Shepherds German Shepherds german.html
Yorkshire Terriers Yorkshire Terriers yorkshire.html
2. On the home page,linkthe words German Shepherd and
Yorkshire Terrier totheir pages.
3. On the home page,remove the words “Home Page” after
“Dogs.”
4. On the Chesapeake BayRetriever,German ShepherdandYorkshire
Terrier pages,put the page headings in the same font andweight as
the home page (Verdana; bold).
5. Make the page headings of these pages one size smaller than the
heading on the home page,just like on the Chesapeake Bay
Retriever page.
6. Save all pages andclickon the home page’s links tomake sure they
work.
Answers
A. Because most Web servers deal better with lower-case, spaceless file names.
B. It provides site users with a visual distinction between first-level (home) pages and second-level (main section) pages.

31
Create e-mail and external links
Create an e-mail link
1. In a newparagraphbeneaththe list,type the sentence “For more
information, contact info@visibooks.com.”
2. Surroundthe e-mail address withanchor tags,but insteadof
linking it toa Webpage,use the mailto commandtolinkit toan
e-mail program:
For more information, contact
A HREF=”mailto:info@visibooks.com”
info@visibooks.com/A

32
3. Save the page. When you viewit in the browser,it shouldlooklike
this:
How e-mail links work
When someone goes toa Website andclicks on an e-mail link,
it’s supposedtoopen the e-mail programon that person’s
computer andinsert the address intoa newmessage.
If the person’s e-mail programisn’t configuredcorrectly,this
won’t work. That’s whye-mail links shoulduse the e-mail
address as a link: sopeople can enter the address manuallyif
theyhave to.

33
Link to an external site
1. In Notepad,adda newsentence after the last one. Type the
sentence,“Please also visit www.dogs.com.”
2. Surroundthe Webaddress www.dogs.com withthese anchor
tags tolinkit tothe external Website:
A
HREF=”http://www.dogs.com”www.dogs.com/A
Tip: For an external link to work, you must type http:// as part of
the Web address.
3. Save the page.
4. Previewthe page in the browser,then clickon the linktosee if it
links tothe external site www.dogs.com.
5. Close the browser.

34
Insert and align graphics
Capture a graphic from the Web
1. Open a newbrowser window.

35
4. ClickSave Picture As.
5. When the Save Picture windowappears,select the “Dogs” folder
in the Save in drop-down list.
6. Create a newfolder within Dogs called“graphics.”
7. Double-clickon the graphics folder soit appears in the Save in
drop-down list.
8. Clickthe Save button tosave the graphic inside the graphics
folder.
Tip: Creating this separate sub-folder to hold your site’s graphics
makes the site easier to organize and update.

36
Insert a graphic
1. In Notepad,open the Chesapeake BayRetriever page,file name
chesapeake.html.
2. Create a newparagraphunder the main heading.
3. In the newparagraph,insert an image tag:
IMG SRC=”graphics/chessie.gif”
Tip: Notice that in this image tag there’s a “path.” For the image
source, the tag first points to the graphics folder, then to the file name
of the image within it.
folder graphic

37
4. Save the page,then viewit in the browser. It shouldnowlooklike
this:

38
Align a graphic
1. In a newparagraphbelowthe graphic,type in:
Chesapeake Bay Retrievers love water. If you
throw tennis balls in the water, these dogs
will chase them and bring them back until
your arm falls off.

39
2. Save the page andviewit in the browser. The page shouldlooklike
this:
3. GobacktoNotepadandaddthe ALIGN=”left” attribute tothe
IMG tag:
ALIGN=”left”

40
4. Save the page andviewit in the browser (just clickthe “Refresh”
or “Reload” button). It shouldlooklike this:

41
Format a graphic
1. In the Chesapeake BayRetriever page,addthis ALT attribute tothe
IMG tag:
IMG SRC=”graphics/chessie.gif” ALIGN=”left”
ALT=”Chesapeake Bay Retriever”
2. Addthe VSPACE=”4” andHSPACE=”12” attributes as well:
ALT=”Chesapeake Bay Retriever” VSPACE=”4”
HSPACE=”12”
3. Also,addthe BORDER=”1” attribute:
HSPACE=”12” BORDER=”1”
“Alt” text allows visually-impairedpeople toknowwhat a
graphic represents. Alt text alsoallows searchengines toindex
visual content.

42
4. Save the page andviewit in the browser. It shouldnowlooklike
this:
5. Move your cursor ontothe graphic. The “Alt” text—an alternative
text description of the graphic—shouldpopup.
The text shouldbe alignedwiththe topof the graphic.
Tip: If you know the dimensions of a graphic, you can make it load
faster by specifying its width and height in pixels:
HSPACE=”12” BORDER=”1” WIDTH=”150”
HEIGHT=”189”
AnHSPACE of 12 creates a
horizontal spaceof 12 pixels
aroundthegraphic thatnothing
canoccupy
A Borderof 1 creates a1-pixel
borderaroundthegraphic

43
Practice: Insert graphics
A. Why should you specify Alt text for each graphic you insert?
1. Gotowww.visibooks.com/dogpics. Save the German Shepherds
graphic in C:dogsgraphics withthe file name shepherds.gif.
2. Save the Yorkshire Terrier graphic in C:dogsgraphics withthe
file name yorkie.gif.
3. Insert shepherds.gif intothe German Shepherds page in a new
paragraphbelowthe heading.
4. Insert yorkie.gif intothe Yorkshire Terriers page in a new
paragraphbelowthe heading.
5. On the German Shepherds page,type “German Shepherds are
smart dogs” in a paragraphbelowthe graphic.
6. On the Yorkshire Terriers page,type “Yorkshire Terriers are
cute” in a paragraphbelowthe graphic.
7. On bothpages,align the text tothe side of the graphic,as on the
Chesapeake BayRetrievers page.
8. On bothpages,give the graphic a border of 1,vspace of 4,and
hspace of 12.
9. On all three “Dog” pages,put all paragraphtext (not the main
headings) in the arial font,witha size of -1.
Answers
A. Alt text makes it easier for vision-impaired people to understand a page’s content, and makes it easier for search engines to
catalog it.

44

Showing “you are here”
Asite’s navigational systemshouldshowpeople twothings:
where theyare,andwhere theycan go.
Toshowpeople where theyare,make the linkcorresponding
tothe current page intoplain text. This lets users knowthat if
theycan’t gotothat page,theymust be looking at it.
Home | Chesapeake Bay Retrievers | German Shepherds | Yorkshire Terriers
Youarehere
Making the text boldreinforces the “you are here” message.

47
Use graphics as links
1. In Notepad,open the home page. Belowthe bulletedlist of links,in
a newparagraph,insert the Chesapeake BayRetriever,German
ShepherdandYorkshire Terrier graphics:
IMG SRC=”graphics/shepherds.gif”
IMG SRC=”graphics/yorkie.gif”
2. Enclose the first image tag within anchor tags that linkit tothe
Chesapeake BayRetriever page:
A HREF=”chesapeake.html”IMG

Practice: Create a navigation system
A. What’s a good way to show site users “You are here?”
Task: Tomake your Dogs site looklike the site at
www.visibooks.com/dogs.
1. In Notepad,open the German Shepherds page,german.html.
2. Following the Home link,type:
| Chesapeake Bay Retrievers | German Shepherds |
Yorkshire Terriers
3. Make the words German Shepherds bold.
4. Linkthe words Chesapeake Bay Retrievers and
Yorkshire Terriers totheir corresponding pages.
5. Save the page.
6. Using the same system,create navigation links for the Yorkshire
Terriers page. Then save the page.
7. On the home page,linkthe German Shepherds graphic tothe
German Shepherds page. Dothe same for the Yorkshire Terriers
graphic.
8. Take out the linkborders of these graphics.
9. When finished,previewyour Dogs site in the browser. It should
looklike the site at www.visibooks.com/dogs.
Answers
A. Make the link corresponding to the current page bold, and plain text (no longer a link).

Change page, link colors
Change background color of page
1. Open the home page in Notepad.
2. In the BODY tag,addthe attribute BGCOLOR=”#ffffcc”:
BODY BGCOLOR=”#ffffcc”
3. Save the page andviewit in the browser. The backgroundcolor of
the page shouldnowbe pale yellow.
Hexadecimal colors
The ffffcc that stands for pale yellowis a hexadecimal
color. Hexadecimal colors allowyou tospecifycolors more
preciselythan you can withwords. For example,you coulduse
the attribute BGCOLOR=yellow in the bodytag andthe page
backgroundwouldturn bright yellow,but if you used
BGCOLOR=pale yellow,that wouldn’t work.
For shades of color,hexadecimals must be used. Theywork
like this:
Computers showcolor as a mix of red,green andblue. In
hexadecimal colors,the first pair of letters or numbers signify
red,the secondpair signifygreen,andthe thirdpair signify
blue:
Red Green Blue
ff ff cc

51
Hexadecimal colors, continued
The color values gofromthe maximumamount of color (ff)
tonocolor at all (00):
Max Mid-range None
ff cc 99 66 33 00
Navyblue wouldbe shown in hexadecimals as nored(00),no
green,(00),anda little bit of blue (66):
000066
Alist of hexadecimal color codes is postedat:
www.webmonkey.com/reference/color_codes

52
Change link colors
1. In the home page,addthe attribute LINK=”#ff0000” tothe
BODY tag:
BODY BGCOLOR=”#ffffcc” LINK=”#ff0000”
This makes the links on the page showup in red.
2. Addthe attribute VLINK=”#00ff00” tothe BODY tag:
BODY BGCOLOR=”#ffffcc” LINK=”#ff0000”
VLINK=”#00ff00”
This makes visitedlinks showupin green.
Tip: Visited links are links to pages that have already been viewed in
the browser.

53
3. Save the page andviewit in the browser. The links on the page
shouldeither be redor green.
Consistent link colors
Linkcolors shouldbe consistent throughout a Website. If the
links on one page are red,theyshouldbe redon everypage.
Learning that “redequals link” once is mucheasier for people
than having tofigure out the linkcolor for eachpage or section
of a site.

Lay out pages using tables
Tables and Web page layout
Almost all professional-qualityWebsites are laidout using
tables. Just like a spreadsheet has cells that contain numbers,a
table on a Webpage has cells that contain links,graphics,and
text.
The lines on this page clearlyshowits layout withtable cells:
cell cell cell

59
Create a table
1. Create a newfolder on the C: drive called“Travel.”
2. In Notepad,create a home page (file name index.html) titled
“Traveling Down South.” Save it in the Travel folder.
Tip: Make sure that your new home page has the correct file name—
index.html—and all necessary tags:
HTML
HEAD
/HEAD
TITLE
Traveling Down South
/TITLE
BODY
/BODY
/HTML
3. You’re going tocreate a simple one-row,two-cell table that looks
like this:
links content
4. The first step is tobegin the table. Belowthe BODY tag,begin
your table withthe TABLE tag:
BODY
TABLE
5. Belowthe TABLE tag,start a rowwiththe TR (Table Row)
tag:
BODY
TABLE
TR

60
6. In the table row,start the first cell withthe TD (Table Data) tag:
BODY
TABLE
TR
TD
7. After the TD tag,type the word“links,” then close the cell
withthe /TD tag:
BODY
TABLE
TR
TDLinks/TD
You’ve createdthe first cell in the row:
links content
8. Nowcreate the secondcell in the rowbyadding a TD tag,the
wordContent,andclosing the cell witha /TD tag:
BODY
TABLE
TR
TDLinks/TD
TDContent/TD
links content

61
9. Finishthe table byclosing the rowwitha /TR tag,then closing
the table withthe /TABLE tag:
BODY
TABLE
TR
TDLinks/TD
TDContent/TD
/TR
/TABLE

62
10.You have set upthe basic table. Tomake it possible tosee the table
outlines in a browser,addthe attribute BORDER=”1” tothe
TABLE tag:
BODY
TABLE BORDER=1
TR
TDLinks/TD
TDContent/TD
/TR
/TABLE
11.Save the page,then viewit in the browser. It shouldlooklike this:

63
Format a table
1. Nowyou’ll extendthe table. In Notepad,addthe WIDTH=”100%”
attribute tothe TABLE tag:
BODY
TABLE BORDER=1 WIDTH=”100%”
TR
TDLinks/TD
TDContent/TD
/TR
/TABLE

64
Percentage vs. fixed-width tables
When laying out a page using a table,set the table’s widthat
100%. That way,the contents of the page can stretchtofill the
whole monitor,regardless of the monitor’s resolution.
If you want it tofit a fixed-widthtable on all monitors,you’re
limitedtoa table 580 pixels wide:
640 pixels

low-
resolution

- 20 pixels

contentis indented
fromthesides ofthe
browser
- 40 pixels
20 forthe
vertical
scroll bar,
plus 20 extra
= 580 pixels

available
fortable
Creating pages withfixed-widthtables offers precise control,
but wastes space on higher-resolution monitors:

Page:laid out using a table 580 pixels wide

Monitorusedtoview page:1280 pixels wide

65
3. Remove the table border byspecifying BORDER=”0”:
BODY
TABLE BORDER=”0” WIDTH=”100%”
TR
TDLinks/TD
TDContent/TD
/TR
/TABLE
4. Make the first cell light greybyadding the attribute
BGOLOR=”#CCCCCC” tothe first TD tag:
BODY
TR
TD BGCOLOR=”#CCCCCC”Links/TD
TDContent/TD
/TR
/TABLE

66
6. You’ll notice that the wordLinks is right up against the edge of the
left-handcell. Toadda 16-pixel margin between the edge of the
cells andtheir contents,addthe attribute CELLPADDING=”16”
tothe TABLE tag:
BODY
CELLPADDING=”16”
TR
TDContent/TD
/TR
/TABLE
7. Toeliminate the spacing between cells,addthe attribute
CELLSPACING=”0” tothe TABLE tag:
BODY
CELLPADDING=”16” CELLSPACING=”0”
TR
TDContent/TD
/TR
/TABLE
Cell Padding creates acushion
of pixels betweentheedgeof
thecell andwhat’s insideit.
Cell Spacing is the
spacebetweencells.
Inthis case, 0 pixels

Link to an external site using frames
How touse frames
“Frames” are a waytoput more than one Webpage at a time
on a computer’s screen:
2=CA
2=CA 2=CA!

Alive example of frames can be seen at
www.visibooks.com/frames.
Manysites that usedframes have noweliminatedthem,
returning tosingle-page layouts. That’s because frames have
serious drawbacks:
• Frames are difficult toupdate. Everyscreen involves
three or more pages tokeep trackof: the frameset itself,
andat least twoothers togoin the frames.
• Frame navigation is tricky. Links require special
“targets” that gofrompage toframe.
• Frames often require people toscroll annoyinglyin
more than one place.
However,frames are useful for one thing: theyallowa user to
get backtoa site withone clickwhile clicking throughother
sites linkedtoit. An example of this can be seen in the external
links at www.charuhas.com/sites.html.
The following exercise demonstrates howtouse frames to
provide convenient links toexternal sites.

92
1. On the Golden Gate Bridge page,in a newparagraphbelowthe
first one,type:
Visit the Web site for the Golden Gate bridge at
www.goldengate.org.
www.goldengate.org will be linkedtothe frameset page.
2. Create a newblankpage withfile name framesetgg.html. This will
be the “frameset” page that holds twoother pages.
3. Insert this HTMLcode intothe newblankpage:
HTML
HEAD/HEAD
TITLEGolden Gate Frameset/TITLE
FRAMESET ROWS=50,*
FRAME NAME=topframe SRC=backtogg.html
FRAME NAME=bottomframe
SRC=http://www.goldengate.org
/FRAMESET
/HTML

93
Tip: The ROWS=”50,*” attribute in the FRAMESET tag tells
the frameset to make the top frame 50 pixels high, and to allow the
bottom frame to fill in the rest of the available space beneath it.
The top frame will contain the link back to the Golden Gate Bridge
page. The bottom frame will contain an external site:
www.goldengate.org.
Link back to the Golden Gate Bridge page

The goldengate.org site will display here

4. Save framesetgg.html.
5. Create a newpage withfile name backtogg.html. This is the page
that will contain a linkbacktothe Golden Gate Bridge page.
6. Give the newpage a light greybackground,anda single linkon it:
Back to the Golden Gate Bridge page.
7. Use an anchor tag withthe TARGET=”_top” attribute tolink
backtothe Golden Gate Bridge page:
A HREF=”goldengate.html” TARGET=”_top”Back
to the Golden Gate Bridge page/A

94
Tip:The TARGET=”_top” attribute enables linking to a page
outside of the current frame…
Clickhere Gotonew pageoutsideframe
Back to the Golden Gate Bridge
Page
Golden Gate Bridge Page
…which avoids clicking on the link and having the page come up in
the same frame:
Clickhere Pagecomes up insameframe
Back to the Golden Gate Bridge
Page
Golden Gate Bridge page
8. Make the linkarial,size -1,andbold.
9. Save the page.

95
10.Open framesetgg.html in the browser. It shouldlooklike this:
11.Clickon the Back to the Golden Gate Bridge page link. It
shouldtake you backtothe Golden Gate Bridge page.

96
Tip: To make the frameset look more crisp and clean, try using the

Practice: Layout Navigation
A. Why is it important that navigational links stay in the same place and
order on pages throughout a Web site?
B. What is the minimum number of files that must be used to make a
frameset work?
Task: Make your Travel West Website lookandfunction like the one
at www.visibooks.com/travelwest3.
1. Layout the Rockies page using tables soit looks like the California
page.
Heading for the Rockies page:
Nature in the Rocky Mountains
2. Create pages for three subsections of The Rockies main section:
Streams
Snow
Rock Formations
3. Make sure that these pages are linkedandlaidout just like the
Golden Gate Bridge,Highway101 andBig Sur pages.
Page File name Heading
Streams streams.html Mountain Streams
Snow snow.html Snow in the Rockies
Rock
Formations
rocks.html Rock Formations

98
4. Repeat this process withthe Midwest section of the site. The
subsections of the Midwest section are:
St. Louis
Chicago
DeMoines
Page File name Heading
Midwest midwest.html Cities of the Midwest
St. Louis stlouis.html St. Louis
Chicago chicago.html Chicago
DeMoines demoines.html DeMoines
5. On the Chicagopage,insert a one-row,one-cell,fixed-widthtable
200 pixels wide,withcell padding of 4. Color it pale yellow
(BGCOLOR=”#ffffcc”).
6. In this table,put the sentence,“In the past, Chicago was home
to Al Capone, Mayor Daley, and the nation’s biggest
stockyards.”
7. On the St. Louis page,linktothe external Website
www.stlouis.comusing frames.
Paragraph for St. Louis page:
Find out what’s going on in St. Louis at
www.stlouis.com.
8. When you’re done,open the Travel West site in the browser. It
shouldlookandfunction like the one at
www.visibooks.com/travelwest3.

Interactivity
• Insert META tags
• Create forms
• Format text with style sheets
• Employ templates
• Upload sites to a Web server

100
Insert META tags
1. In Notepad,open upthe home page of the Travel West Website.
2. Beneaththe HEAD andsignature (!--your name--) tags,
insert the first META tag for describing the site’s contents:
HEAD
META NAME=”description” CONTENT=”This is
the Travel West Web site. It contains
information about vacationing in California,
the Rockies and the Midwest.”
/HEAD
META tags
METAtags are HTMLtags that can include a description of
the page,as well as “keywords that provide clues toits content.
METAtags make a page easier tofindandindex bysearch
engines.
METAtags don’t showupon a Webpage. Rather,theyreside
unseen in its HTMLcode.

101
3. Beneaththe “description” meta tag,insert a newMETA tag for
its searchkeywords:
HEAD
META NAME=”description” CONTENT=”This is
the Travel West Web site. It contains
information about vacationing in California,
the Rockies and the Midwest.”
META NAME=keywords CONTENT=”traveling,
travel, west, California, rockies, midwest,
golden gate bridge, highway 101, Big Sur,
streams, snow, rock formations, St. Louis,
Chicago, De Moines”
/HEAD

102
Create forms
1. Create a newpage withfile name infoform.html.
2. Title the page “Request for Information” andsave it in the Travel
West folder on your harddrive.
3. Belowthe BODY tag,type the sentence:
Fill out the following form to get more
information about traveling West:
4. Belowthe sentence,insert a P tag,then insert a FORM tag:
BODY
Fill out the following form to get more
information about traveling West:
P
FORM
/BODY
5. Belowthe FORM tag,create a table with4 rows and2 cells in
eachrow. Make the width50%,give it cellpadding of 4,anda
border of 1.

103
6. In the top three left-handcells,put:
Name:
Address:
E-Mail:
8. In the top right-handcell,insert a text input field. Dothis withan
INPUT tag:
TR
TDName:/TD
TDINPUT TYPE=”text” NAME=”name”
SIZE=”20”/TD
/TR
Tip: The TYPE of this input is “text,” which makes it a textbox.
The NAME of this input is “name,” which is how the server knows
that it’s where people enter their name. The SIZE is 20 characters—
the length of the textbox.

104
9. Save the page andviewit in a browser. It shouldnowlooklike this:
10.Insert textboxes in the cells next toAddress andE-mail as well.
Name the input textbox next toAddress “address,” andname
the input textbox next toE-mail “email.”
INPUT TYPE=”text” NAME=”address” SIZE=”20”
11.Save the page andviewit in the browser. It shouldnowlooklike
this:

14.Remove the border fromthe table andalign the text in the left-
handcells tothe right.
TDP ALIGN=”right”Name:/TD
15.Make the left-handcell in the first row5% wide,andthe right-
handcell in the first row45% wide.
Tip: By specifying the width of cells in the first row, the cells in the
rows beneath will assume the same widths.
16.Save the page,viewit in the browser,andit shouldlooklike this:

107
17.Open the home page in Notepadandadda newparagraph:
Get more information about Western Travel
mailed to you
18.Linkthis sentence toinfoform.html.
19.Save the page andviewit in the browser. It shouldlooklike this:
20.Clickon the linksentence. It shouldbring upthe page withthe
form.

108
Making a form work
Tomake a formwork,an action must be assignedtoit. Toadd
an action toyour form,addthe ACTION attribute tothe
FORM tag.
Consult withyour Webserver administrator tospecifywhat
action you shouldassign. For example,an action for a form
might looksomething like this:
FORM METHOD=”POST”
ACTION=http://www.yourdomain.com/cgi-
bin/formmail.pl”
This tells the formtopost its data toa programcalled
formmail.pl on at yourdomain.com. This programmight take
the formdata ande-mail it towhomever you choose.

109
Practice: Create forms
1. Create a newpage withfile name favoritesform.html. Title it “My
Favorite Places.”
2. Insert a form,then insert a table withfour rows andtwocells in
eachrow. Fill the cells withthe text andformobjects seen below:
Tip: The HTML code for a drop-down list looks like this:
SELECT NAME=select
OPTIONFirst Choice/OPTION
OPTIONSecond Choice/OPTION
OPTIONThird Choice/OPTION
/SELECT
The HTML code for radio buttons looks like this:
input type=radio name=radios
value=radio1 checked This is radio button

110
3. Put these values in the drop-down list:
California
The Rockies
The Midwest
4. When finished,save the page andpreviewit in the browser. It

111
Use style sheets
The pros and cons of style sheets
Style sheets are a flexible,powerful tool for laying out and
formatting Webpages. Theyalloweverypage in a site toget
displayinstructions fromjust one style sheet.
For instance,if you createda 1,000 page Website using style
sheets,andyou wantedtochange the linkcolor on everypage,
you’donlyneedtochange the linkcolor on one style sheet.
Without style sheets,you’dhave tochange 1,000 individual
pages.
Style sheets can alsocreate displayeffects. An example of this is
at www.visibooks.com. When you roll your cursor over links,
theybecome underlined—if you’re viewing the page withthe
Internet Explorer browser.
That’s the disadvantage of using style sheets: they’re
interpreteddifferentlybyeachbrowser. Astyle sheet-based
page viewedin Internet Explorer maylookdifferent than it
does in Netscape Navigator or other browsers.

112
Create a style sheet
1. Create a newpage withfile name format.css.
2. Save it in a newfolder on the C: drive calledCSS Site.
Tip: This is a style sheet, not a Web page. It’s a file that gives Web
pages formatting instructions, but isn’t ever seen. It contains no
HTML, and has a different file extension: .css rather than .html.
3. On the blankformat.css page,insert the following instruction:
.bodytext {font-family:Courier New,
Courier, mono; font-size:11pt; font-
weight:bold; color:”#ff0000”; background-
color:#ccccff”}
Here are the component parts of the formatting instructions for
the .bodytext style:
.bodytext The type of text tobe formatted.
font-
family
The fonts in whichthe text shouldbe
displayed. First the computer looks for
Courier New,then Courier,then a
monospacedfont.
The quotes in “Courier New” allow the
computer to read font names with spaces.
font-size The size of the text. Unlike in HTML,style
sheets allowspecific point sizes tobe used.
font-
weight
Boldor plain text.
color The color of the text.
background
-color
Changes the color of the page area directly
behindthe text.

113
4. Save format.css. It shouldlooklike this:

114
Apply a style sheet
1. In Notepad,create a newhome page andput it the CSS Site
folder.
2. Title the home page “Style Sheet Demo Page.”
3. Belowthe BODY tag,type the text CSS Site. Make it a size 1
heading using H1 tags:
BODY
H1CSS Site/H1
4. In a newparagraphbeneathit,type the sentence,“Cascading Style
Sheets are a powerful andflexible tool for formatting Webpages:”
BODY
H1CSS Site/H1
PCascading Style Sheets are a powerful and
flexible tool for formatting Web pages/P

115
6. Belowthe HEAD tag,adda LINK tag that points to
format.css:
HTML
HEAD
LINK REL=stylesheet HREF=format.css
/HEAD
TITLEStyle Sheet Demo Page/TITLE
7. In the P tag,addthe CLASS attribute that points tothe
.bodytext style:
P CLASS=bodytextCascading Style Sheets
are a powerful and flexible tool for
formatting Web pages./P
8. Save the home page andviewit in the browser. It shouldlooklike
this:
The home page’s LINK REL=stylesheet
HREF=format.css tag referredtoformat.css for
formatting instructions.
The paragraphon the page referredtothe .bodytext style on
format.css for formatting instructions.

116
Tip: To use the same stylesheet to format pages throughout a site, just
insert the same LINK tag in each Web page. For instance, if there
were 100 pages in the CSS Site, they could all contain the same
LINK REL=stylesheet HREF=format.css tag
and format body text the same way by using the P
CLASS=”bodytext” tag.

117
Create link effects with style sheets
“Cascading” style sheets
Style instructions can be containedwithin a Webpage itself,
without referring toa separate style sheet. These instructions will
override those of the style sheet,hence the term“Cascading Style
Sheets:”
Aninstructionina
page’s text…
FONT
COLOR=”#ff0000”
This is red
text./FONT
…overrides astyle
instructionforthepage…
STYLE
TYPE=text/css
.greentext { color:
“#00ff00” }
/STYLE
BODY
P
CLASS=”greentext”
This is green text.
…which overrides astyle
instructionforthesite.
LINK REL=”stylesheet”
HREF=”format.css”
/HEAD
BODY
P CLASS=”bodytext”
This is blue text.
The following exercise employs an in-page style.

118
9. In the CSS Site folder,open the home page in Notepad.
10. Belowthe HEAD tag,replace this:
withthis:
STYLE TYPE=text/css
!--
A:link {color:#ff0000; text-
decoration:none}
A:visited {color:#ff0000; text-decoration:
none}
A:hover {color:#00ff00; text-decoration:
underline}
--
/STYLE
11.Belowthe present paragraph,adda newparagraph:
A good resource for learning more about
style sheets is Webmonkey.
12.Linkthe word“Webmonkey” tothe external site
http://www.webmonkey.com. Also,make the wordWebmonkey
bold.
13.Save the page andrefreshit in the browser. When you put your
cursor on the wordWebmonkey,it shouldchange fromredand
plain togreen andunderlined.

119
Practice: Using style sheets
1. Open format.css in Notepad.
2. Addthe following style instruction belowthe .bodytext style:
.heading {font-family: Verdana, Arial,

3. Save format.css.
4. Open the home page andreplace:
STYLE TYPE=text/css
!--
A:link {color:”#ff0000”; text-decoration:
none}
A:visited {color:”#ff0000”; text-decoration:
none}
A:hover {color:”#00ff00”; text-decoration:
underline}
--
/STYLE
withthe original LINK tag:

120
5. Addthe CLASS=”heading” attribute tothe H1 tag.
H1 CLASS=”heading”
6. Save the home page andviewit in the browser. It shouldlooklike

131
Advanced Layout
• Employ background images
• Employ spacer GIFs
• Insert a horizontal rule
• Specify page margins
You’ll create a page that looks like this:

132
Employ background graphics
1. Open Notepad.
2. Create a newpage withall necessaryHTMLtags anda two-cell
table:
Rows: 1
Cells: 2
Width: 100 Percent
Border: 0
Cell Padding: 18
Cell Spacing: 0
3. Save the file on your computer’s Desktopwiththe file name
advlayout.html. Title it Advanced Layout.
4. Give bothcells in the table a darkblue backgroundcolor
(#000099).
5. Make the first cell 10% wide,andthe secondcell 90% wide.

133
6. Gotowww.visibooks.com/advlayout/picsandsave techtool.gif on
your computer’s Desktop. Insert it in the left-handcell.
7. Gotowww.visibooks.com/advlayout/picsandsave bkgd.gif on
your computer’s Desktop. Make it the backgroundof the right-
handcell using the BACKGROUND attribute:
TD WIDTH=”90%” BGCOLOR=#000099
BACKGROUND=”bkgd.gif”
8. In the right-handcell,type the text,“The Magazine for People
Who Like Gadgets.”
9. Make the text arial,size +1,bold.
10.Color the text white.
11.Previewthe page in the browser. It shouldlooklike this:
Tip: Notice the line towards the bottom of the cell where bkgd.gif
begins repeating. It repeats because background graphics tile to fill all
available space in a cell. The cell is 136 pixels tall: 100 pixels for
techtool.gif, plus 36 for Cell Padding (18 pixels at the top and bottom
of techtool.gif).
bkgd.gif is only 123 pixels tall; therefore, there’s 13 pixels of space left
to fill. To fix this, use an image editing program like Photoshop,
Fireworks or Paint Shop pro to make the background image 136 pixels
tall.

134
12.Belowthe first table,insert a three-cell table witha widthof 100%
andcellpadding of 4. It’s border andcellpadding shouldbe 0. Make
the cells equal widthandcolor themblack.
13.In the first cell,enter the text,“Laptops.” In the second,“Cell
Phones,” andin the third,“PDAs.” Make the text white andcenter
it withing the cells.
14.Save the page andviewit in the browser. It shouldlooklike this:

135
Employ spacer GIFs
1. Gotowww.visibooks.com/advlayout/pics andsave spacer.gif on
your computer’s Desktop.
2. Belowthe toptwotables,insert a thirdtable just like the first table.
3. Insert spacer.gif in the left-handcell. Give it a widthof 100 and
height of 1.
TD WIDTH=10% BGCOLOR=#000099IMG
SRC=spacer.gif WIDTH=100
HEIGHT=1/TD
Tip: Most spacer GIFs are 1x1 pixel, which load very quickly online.
This one started out as 50x50 to make it easier to see and save.
4. Change the backgroundcolor of the cell containing spacer.gif to
bright yellow(#ffff00).
Why use spacer GIFs?
Spacer GIFs are usedtostretchtable cells toan exact width.
Theyare transparent,sotheyremain invisible regardless of the
cell’s backgroundcolor.
Aspacer GIF is usedin the exercise below. It keeps the widthof
the left-handcell constant,regardless of the size or resolution
of the screen usedtoviewit.

136
5. Put text in the right-handcell sothe page looks like this when
viewedin the browser:
6. Set the browser tohighresolution—1024x768 pixels. The page
Notice howthe left-handcells in the topandbottomtables staythe
same width,regardless of the widthof the browser usedtoview
them.

137
Insert a horizontal rule
1. Belowthe text in the right-handcell,insert a P tag,then the tag
for a horizontal rule:
You can read our product reviews and also
offer your own opinions and observations on
high tech products.
P
HR
2. This generates a 3-Drule. Togive it a cleaner look,addthe
attributes NOSHADE andSIZE=”1” tothe HR tag:
HR NOSHADE SIZE=”1”
3. Place text belowthe horizontal rule soit looks like this when
viewedin the browser:

138
Specify page margins
1. In the BODY tag,addthe LEFTMARGIN,RIGHTMARGIN,
TOPMARGIN,MARGINWIDTH andMARGINHEIGHT attributes.
Give themall a value of zero:
BODY LEFTMARGIN=0 RIGHTMARGIN=0
TOPMARGIN=0 MARGINWIDTH=0
MARGINHEIGHT=0
Tip: The LEFTMARGIN, RIGHTMARGIN, and MARGINWIDTH
(along with TOPMARGIN and MARGINHEIGHT) attributes are
redundant to account for browser differences: Internet Explorer
recognizes LEFTMARGIN, RIGHTMARGIN and TOPMARGIN,
while Netscape Navigator recognizes MARGINWIDTH and
MARGINHEIGHT.
2. Specifya backgroundcolor of white (#ffffff) for the cell
containing the page’s text. Specifya backgroundcolor of darkblue
(#000099) for the page itself.

139
3. Save the page andviewit in the browser. When you’re done,it

Practical JavaScript
• Enable rollover graphics
• Open new windows
• Validate form input
You’ll incorporate functions that look like this:

Enable rollover graphics
What is JavaScript?
JavaScript is a programming language that sits in the HTML
code of a Webpage. It’s not an industrial-strengthlanguage
like C++,Java,or Perl that’s usedtoprogramWebservers.
Rather,JavaScript is usedtoperformsimple functions within
Webpages.
The following section shows you howtoemployJavaScript’s
three most useful functions. It won’t teachyou howtowrite
programs in JavaScript. Learning a programming language is
just that: learning a newlanguage,whichcan take months or
years tomaster. Rather,you’ll learn howtoobtain functioning
JavaScript scripts andmodifythemtodowhat you want.
This approachis fast andeffective. There are thousands of
JavaScript scripts available for free on the Webthat perform
anything you’dwant todoin a Webpage—all you have todo
is customize them.
Working with source code
Sometimes you’ll see a Webpage andsaytoyourself,“I
wonder howtheydidthat?” Byviewing the page’s HTMLand
JavaScript source code,you can findout.
You can alsocopysource code,paste it intopages you’re
working on,andmodifyit. Since that’s soeasytodo,source
code for Webpages isn’t usuallycopyrighted.
The following exercise shows you howtocopy,paste,and
modifyan existing JavaScript toput rollover graphic links on
your Webpages.

143
View source code
1. Create a folder on your harddrive called“rollover,” at C:/rollover.
2. Using the browser,gotowww.visibooks.com/advancedlayout.
3. Viewthe page’s source code byclicking View,then Source.

144
Copy source code
1. Acopyof Notepadwithadvancedlayout(1) in the title bar will
appear. Select all the HTML,then copyit.
2. Create a newblankpage in Notepadandpaste all the copied
HTMLcode intoit.
3. Save the page at C:rollover as index.html.
4. Create a folder within the rollover folder calledgraphics:
C:rollovergraphics.
5. Gotowww.visibooks.com/rolloverpics. Capture all six graphics
there andsave themin the graphics folder.

145
6. Gotowww.visibooks.com/rollover.
The graphics in the navigation bar are
rollover links:
7. Viewits source code andhighlight all
the code between andincluding the
SCRIPT and/SCRIPT tags.
It’s between the HEAD and
/HEAD tags:
8. Copythis JavaScript code.
9. Paste the JavaScript code between the HEAD and/HEAD tags
in index.html.

146
Modify source code
1. You’ll notice that the names of the graphics specifiedin the
JavaScript (laptops2.gif,laptops.gif,
cellphones2.gif…) don’t correspondwiththe names of the
graphics in your graphics folder.
Modifythe source code tospecifythe correct file names for your
graphics:
img1on = new Image();
img1on.src = graphics/lapbright.gif;
img2on.src = graphics/cellbright.gif;
img3on.src = graphics/pdabright.gif;
img1off = new Image();
img1off.src = graphics/lap.gif;
img2off.src = graphics/cell.gif;
img3off.src = graphics/pda.gif;
Graphics

147
2. Gobacktowww.visibooks.com/rollover in the browser,andview
the page’s source code. Scroll down until you see the code for the
secondtable,the one that defines the blacknavigation bar.
3. Highlight andcopythe anchor tag withthe onMouseOver and
onMouseOut attributes,the closing anchor tag (/a),andthe
image tag inside them. It links tolaptops.html:
4. In index.html,get ridof the twocells withthe |characters in them.
