特殊的css样式

在一定范围大小变化的div

.div
{
	auto;
	height:auto;
	min-height:100px;
	min-100px;
	max-height:200px;
	max-200px;
}

圆的css样式

.a
{400px;
height:400px;
background-color:#06F;
top:800px;
left:800px;
-moz-border-radius:200px;
-webkit-border-radius:200px;
border-radius:200px;
}

三角形

<style>
.t{
  50px;
  border-style:solid;
  border-color:#a6a2f7 #fff;
  border-0 50px 50px 50px;
}
</style>

 div实现滚动条 (某些情况下可以替代iframe)

<style>
.gb { overflow:auto; white-space:normal; height:100px; padding:3px;}
</style>
<div class="gb"></div>

其中高度height和overflow是必须设置的！

ps:在IE下有的时候水平滚动条会出来，但是事实上，水平滚动条不没有实际的用途，貌似这个是IE的ｂｕｇ，解决方法：overflow-x: hidden

　加上这个．把水平滚动条隐藏掉
