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;
}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
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
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

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;

</p>
<p><label for="password" >Username</label>
<input type="password" id="password" name="pass" />
