css如何匹配第几个li元素并设置样式:
如果有一个li元素列表，如果想设置指定位置li的样式。
这个在以前可能需要稍微麻烦一些，比如在这个要设置的li元素上添加一个class或者id之类。
但是上面的方式不够灵活，下面介绍一下如何通过伪类选择器实现此功能。
代码实例:

<!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">#items{  width:900px;  height:auto;  margin:0 auto;  padding:5px 0;  clear:both;}#items ul, #items li{  list-style:none;}#items li{  width:500px;  height:28px;  text-align:left;  padding-left: 0px;  line-height:28px;  border-bottom:dashed 1px #CCC;  cursor:pointer;}#items ul li:nth-child(2){color:green;}</style></head><body><div id="items">  <ul>    <li>蚂蚁部落欢迎您，只有努力奋斗才会有美好的未来</li>    <li>没有任何人一开始就是高手，必须要好好学习</li>    <li>本站的url地址是softwhy.com</li>    <li>每一天都是新的，所以要好好真心当前时间</li>    <li>div css教程里面有大量详实的代码</li>  </ul></div></body></html>

上面的代码可以将第二个li元素的字体颜色设置为绿色。
:nth-child可以参阅CSS的伪类选择符E:nth-child(n)一章节。
