做网页设计时经常要用到各种形状的图形，对于规则的图形很简单，但是对于不规则的图形，一般我们都是用图片，今天就在这里教大家怎样用css代码写出各种规则不同的图形
1.正方形
#square {width: 100px;height: 100px;background: red;}
2.长方形
#rectangle { width: 200px; height: 100px; background: red;}
3.左上三角
#triangle-topleft { width: 0; height: 0; border-top: 100px solid red; border-right: 100px solid transparent; }
4.右上三角
#triangle-topright { width: 0; height: 0; border-top: 100px solid red; border-left: 100px solid transparent;}
5.左下三角
#triangle-bottomleft { width: 0; height: 0; border-bottom: 100px solid red; border-right: 100px solid transparent; }
