如何利用CSS实现三角形效果:
建议:尽可能的手写代码,可以有效的提高学习效率和深度。
有时候我们经常发现有些矩形的某个地方会出现三角形效果,感觉挺神奇的,当然可以使用背景图片实现,这里简单介绍一下不采用背景图片的效果。代码如下:

<!DOCTYPE html><html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><meta name="author" content="http://www.softwhy.com/" /><title>蚂蚁部落</title><style type="text/css">.parent{  width:300px;  height:100px;  margin:40px auto;  background-color:green;  position:relative;}.square{  width:0px;  height:0px;  border-bottom:10px solid white;  border-left:10px solid white;  border-right:10px solid green;  border-top:10px solid green;  position:absolute;  left:-20px;  top:10px;}</style></head><body><div class="parent">  <div class="square"></div></div></body></html>

原理很简单,可能上面的代码还不够明显,那么请看下面这个代码实例就一目了然了。

<!DOCTYPE html><html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><meta name="author" content="http://www.softwhy.com/" /><title>蚂蚁部落</title><style type="text/css">div{  width:0px;  height:0px;  border-bottom:10px solid green;  border-left:10px solid blue;  border-right:10px solid red;  border-top:10px solid black;}</style></head><body><div></div></body></html>
