纯css画三角形/梯形(兼容ie6)
代码很简单也很容易理解,及用css盒模型来实现效果实例:宽高为0的话是三角形,否则是梯形Document.triangle{width: 0;height: 0;border-style: solid;border-color: red transparent transparent transparent;border-wid

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<style type="text/css">
.triangle{
width: 0;
height: 0;
border-style: solid;
border-color: red transparent transparent transparent;
border-width: 12px;
}
.trapezoidal{
width: 12px;
height: 12px;
border-style: solid;
border-color: green transparent transparent transparent;
border-width: 12px;
}
</style>
</head>
<body>
<div class="triangle"></div>
<div class="trapezoidal"></div>
</body>
</html>
效果:
当然也可以把另外三遍设为 *背景色*来实现效果,也可以尝试下把三边设为不同的颜色,宽度效果也很炫酷
为了兼容ie6,border-style和font-size,line-height,overflow都要改下
#test {
height:0;
width:0;
overflow: hidden; /* 这里设置overflow, font-size, line-height */
font-size: 0; /*是因为, 虽然宽高度为0, 但在IE6下会具有默认的 */
line-height: 0; /* 字体大小和行高, 导致盒子呈现被撑开的长矩形 */
border-color:#FF9600 #3366ff #12ad2a #f0eb7a;
border-style:solid dashed dashed dashed;/*ie6不支持颜色透明,可将边框设为dotted或dashed*/
border-width:20px;
}
效果同上
更通用的,不用考虑兼容性的写法,用字符实现三角形
