我有以下html,我希望它与现在看起来完全相反,但我已经尝试了很多,没有什么进展顺利,具体我希望A链接位于链接的顶部,并且B在它下面,而C在A下面,依此类推......我试图将z-index设置为它们但是它没有工作.请向我解释我的错.
HTML:
<html>
<head>
<title>Test page</title>
<link href="style.css" type="text/css" rel="Stylesheet" media="screen" />
</head>
<body>
<div class="d1">
<a href="#" class="a1" style="background-color: #000;">A</a>
<ul class="b1">
<li>
<a href="#" class="a2" style="background-color: #222;">B</a>
</li>
<li>
<a href="#" class="a2" style="background-color: #444;">C</a>
</li>
<li>
<a href="#" class="a2" style="background-color: #666;">D</a>
</li>
<li>
<a href="#" class="a2" style="background-color: #888;">E</a>
</li>
</ul>
</div>
</body>
</html>
CSS:
div.d1
{
width: 100px;
height: 160px;
float: left;
margin: 0 auto;
padding: 10px 50px 15px 50px;
background-color: Red;
}
a.a1
{
display: block;
width: 100px;
height: 130px;
float: left;
margin: 0 auto;
padding: 30px 0 0 0;
}
a.a1:hover
{
color: Red;
}
ul.b1
{
display: block;
width: 100px;
float: left;
position: relative;
left: 25px;
top: -160px;
list-style: none;
margin: 0;
padding: 0;
}
ul.b1 li
{
display: block;
width: 25px;
height: 160px;
float: left;
z-index: -1;
}
ul.b1 li a.a2
{
display: block;
width: 100px;
height: 130px;
margin: 0 auto;
padding: 30px 0 0 0;
}
ul.b1 li a.a2:hover
{
color: Red;
}
你需要给<a>定位,因为z-index要工作它需要将定位设置为一个非static最简单的值,通过将其设置为relative
示例: http ://jsfiddle.net/2JsvU/
a {
position: relative;
z-index: 5;
}
