1. 将网页或元素居中
HTML:
<div class="wrap"> </div><!-- end wrap --> CSS:
.wrap { width:960px; margin:0 auto;}
2.Sticky Footer (让页脚永远停靠在页面底部,而不是根据绝对位置)
HTML:
<div id="wrap"> <div id="main" class="clearfix"> </div> </div> <div id="footer"> </div>
CSS:
* { margin:0; padding:0; } html, body, #wrap { height: 100%; } body > #wrap {height: auto; min-height: 100%;} #main { padding-bottom: 150px; } /* must be same height as the footer */ #footer { position: relative; margin-top: -150px; /* negative value of footer height */ height: 150px; clear:both;} /* CLEAR FIX*/ .clearfix:after {content: "."; display: block; height: 0; clear: both; visibility: hidden;} .clearfix {display: inline-block;} /* Hides from IE-mac */ * html .clearfix { height: 1%;} .clearfix {display: block;} /* End hide from IE-mac */
3.跨浏览器最小高度设置

.element { min-height:600px; height:auto !important; height:600px; }

CSS:
.transparent { /* Modern Browsers */ opacity: 0.7; /* IE 8 */ -ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=70)"; /* IE 5-7 */ filter: alpha(opacity=70); /* Netscape */ -moz-opacity: 0.7; /* Safari 1 */ -khtml-opacity: 0.7; }
