width和padding之间的关系介绍:
本章节简单介绍一下width和padding之间的关系。
主要的疑惑在于,width到底包不包含padding,其实他们的关系非常的单纯,根本不搭调。
之所以会有很多朋友将其搞混是因为他们将width属性和元素的宽度这两个概念混为一谈了。
width属性值并不一定就是元素的实际宽度,看如下代码实例:

 

<!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">#top{  width:300px;  height:150px;  background:#CCC;  margin-bottom:20px;}#bottom{  width:300px;  height:150px;  background:#CCC;  margin-bottom:20px;  padding-left:50px;}</style></head><body><div id="top">蚂蚁部落</div><div id="bottom">蚂蚁部落</div></body></html>
Copy after login

 

从上面的代码可以看到width就是width,padding就是padding。
