Objectives for this workshop series
● To learn the basic skills involved in building a
small website for a course or section.
● To actually build such a web site, and to do a
good job of it.
● To engage in practices that minimize the labor
required to do so.
● To make your teaching practices more visible
on the web.
● To be able to read various versions of HTML
and CSS in other places on the web.

Objectives for today’s workshop
● To learn the basics of CSS, the W3C’s
technology for informing browsers how your
content should be displayed.
● To understand the syntax of CSS, methods for
applying it to your HTML, and some of the
possibilities for using CSS for styling your web
pages.
● To understand why writing semantic rather
than presentational HTML results in a
consistent look for a site and easier
maintenance and updating.

Details, details ...
● I’m going to be moving over a lot of details
rather quickly today.
● You don’t need to memorize them all.
– There are great references on the web, of course.
– This presentation will be online in a few days.
– What’s important is that you pick up major concepts
and work along with them.
– Come talk to me in my Lead TA office hours if you
have questions!
● A collection of useful links is online at
http://is.gd/todoho.

What you won’t learn in these
workshops
● Everything about every version of HTML.
● Everything about producing cutting-edge designs.
● How to produce web sites with active content.
● More than a little bit about search-engine optimization.
WHICH IS TO SAY …
● Some of the information you’ll get here is partial or
moderately simplified (but it’s honest and, I think, sufficient).
● You’re not going to walk out of here with the skills to be a
professional web designer.
● However, you will walk out of here knowing enough to
present your content to your students – and the world – in a
way that reflects positively on you.

Reminders from last time
● HTML is the standard language for displaying
content on web sites.
● An HTML document (“web page”) is a text file with
markup (“tags”) that indicate the structure of the
document to machines that render or otherwise
interpret it.
● Your HTML should focus on describing the
document’s structure, rather than its appearance.
– To put it another way, you should separate content from
information about its presentation.
– Describing the appearance of well-structured content is
the function of CSS.

Tags you’ll see, but shouldn’t use
 – bold text
<big></big>, – to change text size
<blink></blink> – primarily used to ensure that
people despise you.
<center></center> – for centering text
 – for font size and face
 – italic text
, – subscript, superscript.
 – underlined text

A minimally acceptable XHTML
document
● The <!DOCTYPE> declaration is (to you) a string of gibberish whose purpose is to
tell the browser what flavor of HTML you’re using.
● The xmlns= attribute on the <html> tag tells XML parsers how to parse the HTML.
● You can just look up these values, or (even better) use existing documents as
templates.

How CSS works
● CSS information consists of a set of rules,
each of which is applied to a well-formed HTML
document.
● Each rule consists of a selector and a
declaration.
● The selector indicates which chunks of HTML
the rule applies to.
– Selectors can be simple or very complex. You can
get a lot of traction out of very simple selectors.
● The declaration indicates what the content
selected by the selector should look like.

An example: what <h1> looks like
● The selector here simply tells the browser that
the declaration applies to (controls the
appearance of) every <h1> tag.
● Like HTML, CSS ignores extra white space.
– This means that you could just as well do this:
h1 {font-family; Arial; font-size: 36pt;
text-align: center;}
h1 {font-family: Arial;
font-size: 36pt;
text-align: center;}

Some attributes are for any tag
● <tag id="something">
– Attaches a unique ID to an individual tag for some
purpose of your own.
● <tag class="something something_else">
– Indicates that the tag belongs to one or more
groups that you yourself designate for some
purpose of your own.
● <tag style="some valid styling information">
– This is a poor overall strategy for styling your text,
but not a bad way to see quickly how things look.

More examples
p,td,li {font-family: "Times New Roman";
font-size: 12pt;
margin-bottom: 0;}
– You can specify that the same declaration apply to
multiple selectors.
p.first-paragraph {margin-top: 0;}
– You can restrict the selector to specific classes of
tags.
p#abstract {font-style: italic;}
– You can restrict the selector to specific unique IDs
of tags.

#abstract {font-style: italic;}
.abstract {font-style: italic;}
● You can specify that tags be selected by ID (the first
example) or by class (the second example) regardless
of what tag belongs to that class.
● For example, the second rule will match either of the
following and render the text inside the tag in italics:
This paper pointlessly
compares several characters in later Dickens
novels.
This paper compares the eponymous characters
in Martin
Chuzzlewit and David Copperfield.
● Note that it’s best to tag your text with classes and IDs
that are meaningful to you.

li ol li {margin-top: 0;}
#nav li ul li a {text-decoration: none;}
#nav > li {list-style-type: none;}
– The first rule means “don’t use a top margin on any list item
that is inside an <ol> tag that is inside another <li> tag.”
– The second rule means “don’t underline any <a> tag that is
inside a list item that is part of an underlined list that is
inside a list item that is inside a block with the ID nav.”
– The third rule means “don’t display a bullet or number for
any list item that is the immediate child of the element with
the ID nav (but don’t apply this rule if the <li> element is a
more remote descendant of the nav element than being its
immediate child).”
More complex selectors

Tags that do nothing (that’s visible)
●
 – marks an inline group of text
for some purpose of your own.
I thought that 1Q84
was a very disappointing novel.
●
<div></div> – marks a block-level group of text
for some purposes of your own.
<div class="document-header">
I was very disappointed by 1Q84.
However, I quite enjoyed Infinite Jest.
</div>

So, where do you put style information?
● In the style attribute of individual tags.
– In this case, you don’t need a selector: the tag itself is
the selector.
<li style="font-style: italic;">First item</li>
● In the <head> section of individual HTML files.
<html>
<head>
<style>
h1 {font-size: 24pt; font-family: Arial;}
</style>
<title>Some Thoughts</title>
</head>
<body> ...

Best practice: in an external style sheet
● All of your CSS rules go in a single plain-text
file.
● You do this in the heading of each HTML
document that uses those CSS rules:
<html>
<head>
<link rel="stylesheet" type="text/css"
href="/content.css" />
<title>Some Thoughts</title>
</head>
● Updating all of the web pages that depend on
that style sheet is then as simple as updating
that style sheet.

So, what can you do with declarations?
● Short version: a lot.
● You can control pretty much every imaginable
aspect of how individual chunks of HTML are
rendered with appropriate declarations.
● The W3C has a complete list of all valid
element properties that can be modified with
CSS.
● There are also about eight billion other useful
online references.

Example: changing the background
body {background: white;}
body {background: rgb(255,255,255);}
body {background: #ffffff;}
– All change the background for the <body> tag (i.e., the whole
page).
– “white” is a standard color name (there are 16 others).
– Nonstandard colors can be used by specifying their red, green, blue
components in hexadecimal, on a scale of 0-FF (which is 0 to 255
in decimal), or with the rgb() specifier.
p.info-box {background: url("paper.png") repeat;}
– Changes the background for every tag with the class attribute
set to “info-box” to whatever image is contained in the file
paper.png, and tiles it so that it fills the whole box that the 
block occupies.

MLA-compliant text
(more or less)
p {font-family: "Times New Roman", Times, serif;
font-size: 12pt;
text-indent: 0.5in;
width: 6.5in;
text-align: left;
margin: 1in;
line-height: 200%;}
● The browser (or other rendering software) will comply
with as many of the declarations as it can.
● Remember that people will view your web pages with
a variety of operating systems, devices, and
software.

A few words about fonts
● For the font to be used, the user must have it installed
on her system.
● There are no fonts that everyone has installed.
– However, the vast majority have Times New Roman (or
Times), Courier New (or Courier), Arial (or Helvetica), and
possibly Comic Sans and Impact.
● You should provide fall-back fonts in case the user
doesn’t have the font you want.
– They’ll be used in decreasing order of preference.
● The last font you use should be a generic name: serif,
sans-serif, monospace, cursive.
p {font-family: "Times New Roman", Times, serif;}

Can’t you just upload fonts to your
web site?
● Yes.
● But …
– The file format for fonts transferred across the web
is not the same as the file format for fonts on your
computer. You have to convert them.
– Fonts are, legally, creative works that take an
incredible amount of work to do well. They are
subject to copyright. You can’t just upload a font
from your computer unless you designed it or
otherwise have permission to use it.
– If the browser has to wait for fonts to download,
the page will render more slowly.

The HTML box model
Say you have an HTML file containing two paragraphs:
<body>
Whatever normcore selvage Schlitz, locavore PBR&B viral.
Butcher pork belly slow-carb, 8-bit kitsch PBR food truck ethical

</body>

● Every block-
level element
is rendered in
a box.
● You can control
a lot about
these boxes.
– Usually,
borders are
invisible,
unless you
explicitly set
them to be
visible.

Padding, border, margin
p {background: aqua;
padding: 0.5in;
border: 2px purple dashed;
margin: 1in;}

Useful layout properties
Property Useful settings
clear left, right, both
display inline, block, list-item, table,
none
width 800px; 80%; 6.5in; 60em
vertical-align top; baseline; middle; bottom; sub;
super
position static; relative; absolute; fixed
top, right,
bottom, left
12px; .25in; 3em; 20%
(use with relative, absolute, or fixed positioning)
float left, right, none

Shorthand properties
p {font: italic small-caps bold 12pt/24pt
"Times New Roman", Times, serif;}
p {font: bold 12pt "Times New Roman";}
● You can specify multiple values for related properties
in a convenient shorthand.
● You can drop some properties (defaults will be used),
provided that what is in there is in the right order.
● Similarly, margin is a shorthand property for margin-
left, margin-right, margin-top, and margin-bottom.
● And background is a shorthand property for background-
color, background-image, background-repeat,
background-attachment, and background-position.

So that’s a lot of detail …
● I can’t remember it all offhand either.
● There are lots of good references on the web,
including at the W3C’s site.
– The W3C has a CSS validator in addition to its
HTML validator.
– If your CSS doesn’t seem to be working, validate it
– and the HTML you’re applying it to – before
tearing your hair out.
– The workshop series website has some useful
links about CSS.

So what’s good design, then?
● There are many approaches to design in the
context of web pages. However, some rules of
thumb …
– Readers don’t parse text on web pages in the same
way that literary theorists read novels.
– You should provide visual cues that help readers to
find crucial information quickly. Leverage the semantic
structure of your documents to do this.
– Use color, size, grouping, spacing, and positioning to
give clues about how items are related to each other.
– Put crucial elements in the same place on every
page, so that readers don’t have to search for them.

How do you learn decent design?
● Look critically and thoughtfully at other web
sites you visit. Ask yourself what does and
doesn’t work well.
– What helps you to parse the web page quickly?
– How could the web page be more easily parsed?
– What is aesthetically appealing about it?
– What is visually ugly about it?
– What ideas, practices, and/or elements can you
appropriate?
● There are links to a few articles about design
on the workshop series website.

Some general principles
● Don’t be afraid of white space.
● Think about why you’re making the choices
you’re making.
● Use color, grouping, etc. to connect related
elements.
● Remember that people scan web pages
instead of reading them straight through. Give
visual cues to help them do this.

A suggestion …
● You won’t really have learned anything today
unless you apply these skills in the near
future.
– Take your HTML-marked section guidelines
handout and make it attractive. Use an external
linked style sheet.
– Start setting up a section website. You can take
one of mine as a model, if you’d like.
– Run your HTML and CSS through the W3C’s
validator and resolve any problems.
– Come talk to me in my office hours if you hit any
snags!
