If you are front end coder you must know how important is to make cross browses, valid CSS and xHTML code. And also you must know how much time we are spending in all those hacks and fixes for various browsers. I've written about some of them earlier on PNG transparency issues, Yellow fields in web form, Vertical align div etc..

Here is the list of 10 hand picked CSS hacks and tricks which can help you in your CSS code and also save some time.

1. Vertical align div

2. Min-Height

 
selector {
min-height:500px;
height:auto; !important
height:500px;
}
 

3. PNG transparency

4. Autoclear

 
.container:after {
content: ".";
display: block;
height: 0;
clear: both;
visibility: hidden;
}
.container {display: inline-table;}
/* Hides from IE-mac \*/
* html .container {height: 1%;}
.container {display: block;}
/* End hide from IE-mac */
 

5. Reset CSS

 
html, body, div, span, applet, object, iframe, h1, h2, h3, h4, h5, h6, p, blockquote, pre, a, abbr, acronym, address, big, cite, code, del, dfn, em, font, img, ins, kbd, q, s, samp, small, strike, strong, sub, sup, tt, var, dl, dt, dd, ol, ul, li, fieldset, form, label, legend, table, caption, tbody, tfoot, thead, tr, th, td {
border:0pt none;
font-family:inherit;
font-size:100%;
font-style:inherit;
font-weight:inherit;
margin:0pt;
outline-color:invert;
outline-style:none;
outline-width:0pt;
padding:0pt;
vertical-align:baseline;
}
table {
border-collapse:separate;
border-spacing:0pt;
}
caption, th, td {
font-weight:normal;
text-align:left;
}
blockquote:before, blockquote:after, q:before, q:after {
content:"";
}
blockquote, q {
quotes:"" "";
}
strong {
font-weight:bold;
}
em {
font-style:italic;
}
* {
margin:0pt;
padding:0pt;
}
 

6. Scrolling Render IE

 
html {
      background : url(null) fixed no-repeat;
     }
 

7. Opacity

 
#transdiv {
filter:alpha(opacity=75);
-moz-opacity:.75;
opacity:.75;
}
 

8. PRE Tag

 
pre {
white-space: pre-wrap; /* css-3 */
white-space: -moz-pre-wrap !important; /* Mozilla, since 1999 */
white-space: -pre-wrap; /* Opera 4-6 */
white-space: -o-pre-wrap; /* Opera 7 */
word-wrap: break-word; /* Internet Explorer 5.5+ */
}
 

9. Li Background Repeat IE

 
<!--[if lt IE 7]>
<style>
#leftnav li { zoom: 1;} /* haslayout=true */
</style>
 
<![endif]-->
