二.在浮动元素后面添加一个空标签:
<!DOCTYPE html><html><head><meta charset=" utf-8"><meta name="author" content="http://www.softwhy.com/" /><title>蚂蚁部落</title><style type="text/css">*{ margin:0px; padding:0px;}#box{ list-style:none; width:150px; overflow:hidden; border:1px solid red; margin:50px;}#box li{float:left;}.clear{clear:both}</style></head><body><ul id="box"> <li>蚂蚁部落一</li> <li>蚂蚁部落二</li> <li>蚂蚁部落三</li> <li>蚂蚁部落四</li> <div class="clear"></div></ul></body></html> 三.各大网站最为推荐的一个方式:
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <meta name="author" content="http://www.softwhy.com/" /> <title>蚂蚁部落</title> <style type="text/css"> .parent{border:2px solid green;} .clearfix{*zoom:1;} .clearfix:after{ content:"."; display:block; height:0; visibility:hidden; clear:both; } .children{ width:100px; height:100px; background-color:red; float:left; } .right{ width:100px; height:100px; background-color:blue; float:right } </style> </head> <body> <div class="parent clearfix"> <div class="children"></div> <div class="right"></div> </div> </body> </html> 上面是清除浮动的几种方式，这里就不多介绍了，更多内容可以参阅相关阅读。
