1.自己写了一个，写完对比了下别人写的发现自己写的太low.故就不写自己太差劲的了。
别人写的我总结优化了一下，如果不用写内容去掉position,content简单也是可以的。
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=gb2312" /> <title>无标题文档</title> <style> .box-wrap { text-align: center; background-color: #d4d4f5; border:1px solid #FF0000; overflow: hidden; /*为了清除浮动*/ } .box-wrap>div { width: 31.33%; padding-bottom: 31.33%;/*是父级元素的宽度的百分比*/ margin:1%; border-radius: 10%; float: left; background-color: orange; position:relative; } .content { position:absolute; width:100%; height:100%; border-radius: 10%; } </style> </head> <body> <div class="box-wrap"> <div class="box"> <div class="content">格子1</div> </div> <div class="box"> <div class="content">格子2</div> </div> <div class="box"> <div class="content">格子3</div> </div> <div class="box"></div> <div class="box"></div> <div class="box"></div> <div class="box"></div> <div class="box"></div> <div class="box"></div> </div> </body> </html>
2.也可以使用伪元素
