当你在做网站的时候可以直接引入css的引入语句如下:
<!-- Framework CSS -->
<link rel="stylesheet" href="css/screen.css" type="text/css" media="screen, projection">
<link rel="stylesheet" href="css/print.css" type="text/css" media="print">
<!--[if IE]><link rel="stylesheet" href="css/ie.css" type="text/css" media="screen, projection"><![endif]-->
