这个实际上是按照5 3 2 0这样的收缩方法描圆角了。嵌套的层次太多,不利于复用了。
一般做圆角矩形分成固定宽高(最容易),固定宽自适应高(一列三行),宽高自适应(三行三列,又称九宫格)
通常采用第二种方法这种得效果不错了。
把圆角底部图片切割出来放在 <div> </div〉套子里面 顶部图片切割出来放在 <h1> </h1> 或者 <p class= "headline "> </p> 作为背景。就OK了
纯css实现了那又如何,钻牛角尖,给自己设置障碍了
------解决方案--------------------http://www.xhtmlhelp.net/webdesign/code/6064.shtml
------解决方案--------------------用background-image属性。如果是固定宽度的矩形就要双层套叠:
<div class= "rounded ">
<div>
<!--content-->
</div>
</div>
如此设置css:
.rounded {
background-color: 背景色;
background-image: url( '顶部圆角区域.jpg ');
