div+css实现圆角边框,代码如下:
<html>
<head>
<style>
#a{
border-left:1px #333 solid;
border-right:1px #333 solid;
width:300px;
height:500px;
}
.b{
height:1px;
overflow:hidden;
border-left:1px #333 solid;
border-right:1px #333 solid;
}
</style>
</head>
<body>
<div>
<div class=”b” style=”margin-left:3px;width:294px;background:#333″></div>
<div class=”b” style=”margin-left:2px;width:296px;”></div>
<div class=”b” style=”margin-left:1px;width:298px”></div>
<div id=”a”>
我能做到的,纯DIV+CSS实现的效果,只能这样了。这里是放置内容的地方,观察一下代码的规律,很容易明白。
代码很简单,a层为放置内容的层,其width值为300,然后向外以2像素的宽度递减。最外一层要加上background为个属性,目的是要将上、下两线条呈现出来。
这里实现了3像素的圆角边框,b层的数量决定了要实现多少个像素边框。建议不要多于3层,最好是2层,即2像素圆角边框,或者1层,因为层数越多,圆角的表现就越不圆滑。在firefox IE6 都通过测试。
</div>
<div class=”b” style=”margin-left:1px;width:298px”></div>
<div class=”b” style=”margin-left:2px;width:296px;”></div>
<div class=”b” style=”margin-left:3px;width:294px;background:#333″></div>
</div>
</body>
</html>
