1.清除浮动的几种方式
(1: 浏览器支持好,不容易出现怪问题(目前:大型网站都有使用,如:腾迅,网易,新浪等等)
<style type="text/css"> .div1{background:#000080;border:1px solid red;} .div2{background:#800080;border:1px solid red;height:100px;margin-top:10px} .left{float:left;width:20%;height:200px;background:#DDD} .right{float:right;width:30%;height:80px;background:#DDD} /*清除浮动代码*/ .clearfloat:after{display:block;clear:both;content:"";visibility:hidden;height:0} .clearfloat{zoom:1} </style> <div class="div1 clearfloat"> <div class="left">Left</div> <div class="right">Right</div> </div> <div class="div2"> div2 </div>
(2: 添加一个空div,利用css提高的clear:both清除浮动,让父级div能自动获取到高度
<style type="text/css"> .div1{background:#000080;border:1px solid red} .div2{background:#800080;border:1px solid red;height:100px;margin-top:10px} .left{float:left;width:20%;height:200px;background:#DDD} .right{float:right;width:30%;height:80px;background:#DDD} /*清除浮动代码*/ .clearfloat{clear:both} </style> <div class="div1"> <div class="left">Left</div> <div class="right">Right</div> <div class="clearfloat"></div> </div> <div class="div2"> div2 </div>
