href

href是 Hypertext Reference的简写，表示超文本引用，指向网络资源位置；

<a href="http://www.baidu.com"></a> 
<link type="text/css" rel="stylesheet" href="common.css">

src

是source的简写，目的是把文件下载到html中；

<img src="img/girl.jpg"></img> 
<iframe src="top.html"> 
<script src="show.js">

作用结果

href用于建立页面和资源的联系
src替换当前内容

注：

当浏览器遇到href会并行下载资源，而不会停止对当前文档的处理（这就是css用link不用@import的原因）
当浏览器遇到src会停止对其他资源的下载和处理，直到该资源下载完毕（这就是script标签放在文档最后比较好的原因）
