background-image:url('back-image.gif');
background-repeat:no-repeat;
padding-left:20px;
}
3. Setting Minimum width for a page
specify a minimum width for any element. This can be particularly useful for specifying a minimum width for a page.
HTML<body>
<div id="container">
CSS
#container {
min-width: 600px;
width:expression(document.body.clientWidth <>
4. Cross Browser Opacity
make an element transperant by setting the opacity level.
.transparent_class {
filter:alpha(opacity=50);
-moz-opacity:0.5;
-khtml-opacity: 0.5;
opacity: 0.5;
}
5. Centering a Website
this technique to center the content.
HTML
<body>
<div id="page-wrap">
<!-- all websites HTML here -->
</div>
</body>
CSS
#page-wrap {
width: 800px;
margin: 0 auto;
}
6. CSS Drop Caps
first letter will be a drop-cap.
p:first-letter {
font-size : 300%;
font-weight : bold;
float : left;
width : 1em;
}
7. CSS Text Shadow
1. value = The X-coordinate
2. value = The Y-coordinate
3. value = The blur radius
4. value = The color of the shadow
h1{
font-size:180px;
line-height:180px;
text-transform: uppercase;
color:#f9f9f9;
position:absolute;
text-shadow:0 1px 1px #ddd;
top:-25px;
left:-20px;
white-space: nowrap;
}
Regular text shadow:
p { text-shadow: 1px 1px 1px #000; }
Multiple shadows:
p { text-shadow: 1px 1px 1px #000, 3px 3px 5px blue; }
Light Shadow
.shadow {
padding: 20px;
border: 1px solid #f0f0f0;
border-bottom: 2px solid #ccc;
-webkit-border-radius: 5px;
-moz-border-radius: 5px;
border-radius: 5px;
}
Pressed
.pressed {
color: #fff;
padding: 20px;
background: #111;
border: 1px solid #000;
border-right: 1px solid #353535;
border-bottom: 1px solid #353535;
-webkit-border-radius: 5px;
-moz-border-radius: 5px;
border-radius: 5px;
}
8. Using !important
By adding !important to your CSS rule, you can increase its precedence over other subsequent rules. e.g. in below code, background-color will be blue and not red due to !important.
.page { background-color:blue !important; background-color:red; }
9. CSS Pointer Cursors
input[type=submit],label,select,.pointer { cursor:pointer; }
10. Perfect Page-Printing with CSS
@media all
{
.page-break { display:none; }
}
@media print
{
.page-break { display:block; page-break-before:always; }
}
11. Auto Resize Large Images
<style type="text/css">
#post_view img { max-width: 146px; height: 112px; width: expression(this.width > 146 ? 146: true); }
</style>
<div id="post_view">
</div>
#png_bg {
background-image: none;
filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(enabled=true, sizingMethod=crop, src='/path/to/image.png');
}
13.Round Corners without imagesThis technique will work in Firefox, Safari, Chrome and any other CSS3-compatible browser. This technique will not work in Internet Explorer.
div {
-moz-border-radius: 10px;
-webkit-border-radius: 10px;
border-radius: 10px;
}
div {
-moz-border-radius-topleft: 10px;
-webkit-border-top-left-radius: 10px;
}
{border:2px solid;border-radius:25px;-webkit-border-radius:25px; /* Safari */}14.Use Shorthand CSSShorthand CSS gives you a shorter way of writing your CSS codes, and most important of all – it makes
the code clearner and easier to understand.
Instead of creating CSS like this
.header {
background-color: #fff;
background-image: url(image.gif);
background-repeat: no-repeat;
background-position: top left;
}
It can be short-handed into the following:
.header {
background: #fff url(image.gif) no-repeat top left
}
15.Understanding Class And IDThese two selectors often confuse beginners. In CSS, class is represented by a dot "." while id is a hash ‘#". In a nutshell id is used on style that is unique and don’t repeat itself, class on the other side, can be re-use.
Class vs. ID
Use a class tag if:
1. The style is used in various places throughout the document.
2. The style is very general.
Use an id tag if:
1. The style is only used once ever in the document.
2. The style is specific to a certain area of the document.
16.Remove outline for WebKit Browsers
When you focus (:focus) on an input element, perhaps you have noticed that Safari adds a blue border around it (and Chrome, a yellow one).
If you would like to remove this border outline, you can use the following style rule (this removes the outline from text fields):
input[type="text"]:focus {
outline: none;
}
17.Easy Web Fonts with Google Font API
<link href="http://fonts.googleapis.com/css?family=Cantarell" rel="stylesheet" type="text/css">

}
20. Opacity and Cross Browser Compatibility
Opacity is basically a way to make different HTML elements transparent
.transparent_class {
/* IE 8 */
-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=50)";
/* IE 5-7 */
filter: alpha(opacity=50);
/* Netscape */
-moz-opacity: 0.5;
/* Safari 1.x */
-khtml-opacity: 0.5;
/* Good browsers */
opacity: 0.5;
