利用div和css制作三角形效果:
本章节介绍一下如何利用div和css实现三角形效果，虽然看起来表神奇，但是原理是非常的简单。
代码如下:
<!DOCTYPE html><html><head><meta charset=" utf-8"><meta name="author" content="http://www.softwhy.com/" /><title>蚂蚁部落</title><style type="text/css">#box{ width:0px; height:0px; border:40px solid white; border-top-color:#930; border-bottom-color:#0C3; border-left-color:#FC0; border-right-color:#009; line-height:0px;}</style></head><body><div id="box"></div></body></html>
其实这个三角形是利用div的边框"挤出"来的，边框由于采用了不同的颜色，所以很好区分，如果只保留一个方位的三角形，可以自行设置边框颜色或者删除边框就可以了。
