1、改变选中文字的背景和颜色

::selection{ /* Safari and Opera */    background:#c3effd;    color:#000;}::-moz-selection{ /* Firefox */    background:#c3effd;    color:#000;}

2、防止火狐滚动条跳动

html{ overflow-y:scroll; }

3、分页打印

.page-break{ page-break-before:always; }

4、使用!important

.page { background-color:blue !important;   background-color:red;}

5、图像替换文字

.header{    text-indent:-9999px;    background:url('someimage.jpg') no-repeat;    height: 100px; /*dimensions equal to image size*/    width:500px;}

标注:text-indent:-9999px; 是将首行左缩进到人看不到的地方

6、兼容浏览器的最小高度

#container{    height:auto !important;/*all browsers except ie6 will respect the !important flag*/    min-height:500px;    height:500px;/*Should have the same value as the min height above*/}

7、对新窗口打开得链接高亮显示

a[target="_blank"]:before,a[target="new"]:before {    margin:0 5px 0 0;    padding:1px;    outline:1px solid #333;    color:#333;    background:#ff9;    font:12px "Zapf Dingbats";    content: "\279C";}

8、美化li序列号

如图:

ol {    font: italic 1em Georgia, Times, serif;    color: #999999;}ol p {    font: normal .8em Arial, Helvetica, sans-serif;    color: #000000;}

9、首字下沉

如图:

p:first-letter{display:block;margin:5px 0 0 5px;float:left;color:#FF3366;font-size:3.0em;font-family:Georgia;}

10、兼容浏览器的opacity

.transparent_class {          filter:alpha(opacity=50);          -moz-opacity:0.5;          -khtml-opacity: 0.5;          opacity: 0.5;      }

11、使用line-height实现垂直居中

line-height:30px;

12、居中布局

body{    width:1000px;    margin:0 auto;}

13、移除ie文本域的垂直滚动条

textarea{    overflow:auto;}

14、移动超链接的虚线框

a:active, a:focus{ outline:none; }

15、ie下元素消失,给该元素添加

position:relative;

16、根据链接不一样,添加不一样的icons

a[href$='.doc'] {    padding:0 20px 0 0;    background:transparent url(/graphics/icons/doc.gif) no-repeat center right;}

17、css手型点击样式

input[type=submit],label,select,.pointer { cursor:pointer; }

18、字母大写

text-transform: capitalize;

19、所有英文大写,且首字母比其他的大

font-variant:small-caps;

20、高亮文本框,不支持ie

input[type=text]:focus, input[type=password]:focus{    border:2px solid #000;}

21、移除img边框

a img{ border:none; }

22、用label实现无表格表单

HTML Code

<form method="post" action="#" ><p><label for="username" >Username</label><input type="text" id="username" name="username" /></p><p><label for="password" >Username</label><input type="password" id="password" name="pass" /></p><p><input type="submit" value="Submit" /></p></form>

CSS Code

p label{    width:100px;    float:left;    margin-right:10px;    text-align:right;}
