我无法使用外部样式表更改背景颜色.当我尝试使用内部样式表时,它的工作完美.这是代码.
ext1.css
<style>
body{
background-color: red;
}
ul{
color:green;
}
:link{
color:aquamarine;
}
p{
font-family:"arial";
font-size:20px;
}
</style>
HTML DOC
<!doctype html>
<html>
<head>
<title> Defining external style sheet</title>
<link href="ext1.css" rel="stylesheet" type="text/css">
</head>
<body>
<ul>
<li> <a href="#Home">Home</a></li>
<li> <a href="#News">News</a></li>
<li> <a href="#Contact us">Contact</a></li>
<li> <a href="#About">About</a></li>
</ul>
<p> NOTE: We use href="#" for test links , in real web sites we will use URL's </p>
