css如何实现li元素在父元素中平均分布效果:
在实际应用中，通常父元素中有一排子元素，并且这些子元素能够在父元素中均匀分布。
虽然效果简单，实现的方式也各有不同，但是对于一些初学者可能会构成一些困扰。
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>*{  margin:0px;  padding:0px;}#box{  width:625px;  border:1px solid red;  overflow:hidden;  margin:50px;}#ul_box{width:630px;}ul li{  width:100px;  height:30px;  margin-right:5px;  list-style:none;  float:left;  background:#CCC;  text-align:center;  line-height:30px;}</style></head> <body><div id="box">  <div id="ul_box">     <ul style="overflow:hidden">      <li>蚂蚁部落一</li>      <li>蚂蚁部落二</li>      <li>蚂蚁部落三</li>      <li>蚂蚁部落四</li>      <li>蚂蚁部落五</li>      <li>蚂蚁部落六</li>    </ul>  </div></div></body> </html>

上面的代码实现了导航栏在父元素中均匀分布的效果，并且两端都没有空隙，只有中间有空隙。
实现原理:
其实实现的原理非常的简单，就是li元素浮动以后，然后设置右外边距，再将父元素ul_box（其实用ul元素也是可以的）宽度设置为ul的宽度，也就是630（包括li元素的宽度还有外边距），这个时候自然左右边会有空隙，然后只要使用最外层的box父元素进行一下overflow截取就可以了。
