12. LETS GET THING FROM THE
BEGINNING

13. fluid elastic fixed

14. VIEWPORTS
<meta name=”viewport” content=”width:device-width”>
always use it for mobile and fluid designs

15. MEDIA QUERIES
CSS 2.1
<link rel="stylesheet" type="text/css" href="core.css"
media="screen" />
<link rel="stylesheet" type="text/css" href="print.css"
media="print" />
CSS3
<link rel="stylesheet" type="text/css"
media="screen and (max-device-width: 480px)"
href="shetland.css" />

16. WAIT THERE IS MORE!!
<link rel="stylesheet" type="text/css"
media="screen and (max-device-width: 480px) and
(resolution: 163dpi)"
href="shetland.css" />
@media screen and (max-device-width: 480px) {
.column {
float: none;
}
}
@import url("shetland.css") screen and (max-device-width:
480px);

17. AND MORE
@media only screen and (min-device-width : 320px)
(max-device-width : 569px) {...}

18. AND MORE
@media only screen and (min-width : 480px) { .box
{ width:200px; height:200px;
background:yellow; } }
@media only screen and (max-width : 320px) { .box
{width:200px; height:200px; background:red; } }

19. DEVICE-WIDTH
Question:
Is max/min-width the same as max/min-device-width?
Answer:
If you set width=device-width, then max/min-width is the same
as max/min-device-width in portrait mode, and different when
in landscape mode. In short, the difference is max/min-width
will update when you rotate the screen, whereas, max/min-
device-width won't.

20. DEVICE-PIXEL
device-pixel-ratio could help you know the resolution of the device
screen, iPhone 4 and certain other smartphones have pixel ration equal
or higher than 1.5, so if you want to target high resolution devices, you
can use the media query below:
@media only screen
and (-webkit-min-device-pixel-ratio : 1.5),
only screen and (-o-min-device-pixel-ratio: 3/2),
only screen and (min-device-pixel-ratio : 1.5) {
.imagebox {background:(url:"images/high/demo.jpg");}
}
image will be downloaded even if the page doesn't fit the rule above!!

21. ORIENTATION
iPad introduced 'orientation' to help with detecting orientation change, below
is how you can specify landscape and portrait style
/* iPads (landscape) ----------- */
@media only screen and (min-device-width : 768px) and (max-
device-width : 1024px) and (orientation : landscape) {
/* Styles */
}
/* iPads (portrait) ----------- */
@media only screen and (min-device-width : 768px) and (max-
device-width : 1024px) and (orientation : portrait) {
/* Styles */
}

•p{font-size:1.3em;}
add html{font-size:16px; } just to be sure

<link rel="stylesheet"
media="only screen and (-webkit-
min-device-pixel-ratio: 2)"
type="text/css"
href="../iphone4.css" />

57. HIDE NAVIGATION
// When ready...
window.addEventListener("load",function() {
// Set a timeout...
setTimeout(function(){
// Hide the address bar!
window.scrollTo(0, 1);
}, 0);
});
