  只用CSS 来做圆角矩形的技术很早就有了,但是在网页的设计过程中,我们通常用图片

  实现圆角矩形效果。现在网上很多关于无图片实现css圆角矩形的方法,虽说巧妙,但是

  代码冗长,难以做到简洁,所以我觉得很疑惑。

  无图片实现css圆角矩形的原理很简单,就是用1px 的水平线条来堆叠出圆角。

  网上找到一些css圆角矩形的代码,供大家参考一下

  样式1:简洁型css圆角矩形

  css代码:

  .b1,.b2,.b3,.b4,.b1b,.b2b,.b3b,.b4b,.b{display:block;overflow:hidden;}

  .b2,.b3,.b4,.b2b,.b3b,.b4b,.b{border-left:1px solid #999;border-right:1px solid #999;}

  .b1,.b1b{margin:0 5px;background:#999;}

  .b2,.b2b{margin:0 3px;border-width:2px;}
