三角形向下
#triangle-down { width: 0; height: 0; border-left: 50px solid transparent; border-right: 50px solid transparent; border-top: 100px solid red; }
三角向左
#triangle-left { width: 0; height: 0; border-top: 50px solid transparent; border-right: 100px solid red; border-bottom: 50px solid transparent; }
三角向右
#triangle-right { width: 0; height: 0; border-top: 50px solid transparent; border-left: 100px solid red; border-bottom: 50px solid transparent; }

#trapezoid { border-bottom: 100px solid red; border-left: 50px solid transparent; border-right: 50px solid transparent; height: 0; width: 100px; }
圆
#circle { width: 100px; height: 100px; background: red; -moz-border-radius: 50px; -webkit-border-radius: 50px; border-radius: 50px; } /* Cleaner, but slightly less support: use "50%" as value */
椭圆形
#oval { width: 200px; height: 100px; background: red; -moz-border-radius: 100px / 50px; -webkit-border-radius: 100px / 50px; border-radius: 100px / 50px; } /* Cleaner, but slightly less support: use "50%" as value */

在实际的操作中,应该使用transparent透明属性,
例如border-color:#ff3300 #ff3300 transparent transparent;,这同样会有问题,IE6浏览器不支持transparent透明属性,不过没有关系,就border生成三角技术而言,直接设置对应的透明边框的border-style属性为dotted或是dashed即可解决这一问题
