    1. 将网页或元素居中       HTML:
<div class="wrap">  
</div><!-- end wrap -->   
CSS:
.wrap { width:960px; margin:0 auto;}   
3.跨浏览器最小高度设置       CSS:
.element { min-height:600px; height:auto !important; height:600px; }    
7.著名的 Meyer Reset(重置)     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,

/* remember to define focus styles! */  
:focus {  
outline: 0;  
}  
body {  
line-height: 1;  
color: black;   
background: white;  
}  
ol, ul {  
list-style: none;  
}  
/* tables still need 'cellspacing="0"' in the markup */  
table {  
border-collapse: separate;  
border-spacing: 0;  
}  
caption, th, td {  
text-align: left;
