我正在开发一个横向CSS下拉菜单。它仍然适用于IE 7,IE 8,Firefox和Chrome。但我希望顶部<ul>
位于顶层(例如z-index: 100
)。我想要这个,因为顶级<ul>
有一个图形背景,下拉列表只是用css设置样式,并且当前它正在破坏布局。
HTML代码:
<div id="mainMenu">
<ul>
<li><a href="t1">TOP1<!--[if gt IE 6]><!--></a><!--<![endif]-->
<!--[if lte IE 6]><table><tr><td><![endif]-->
<ul>
<li><a href="l1">LINK1</a></li>
<li><a href="l2">LINK2</a></li>
<li><a href="l3">LINK3</a></li>
<li><a href="l4">LINK4</a></li>
</ul>
<!--[if lte IE 6]></td></tr></table></a><![endif]-->
</li>
<li class="center"><a href="t2">TOP2<!--[if gt IE 6]><!--></a><!--<![endif]-->
<!--[if lte IE 6]><table><tr><td></td></tr></table></a><![endif]--></li>
<li><a name="t3">TOP3<!--[if gt IE 6]><!--></a><!--<![endif]-->
<!--[if lte IE 6]><table><tr><td><![endif]-->
<ul class="last">
<li><a href="l5">LINK5</a></li>
<li><a href="l6">LINK6</a></li>
<li><a href="l7">LINK7</a></li>
</ul>
<!--[if lte IE 6]></td></tr></table></a><![endif]-->
</li>
</ul>
</div>
CSS代码
/* style the outer div to give it width */
#mainMenu {
position: absolute;
margin-left: 6px;
margin-top: 180px;
}
/* remove all the bullets, borders and padding from the default list styling */
#mainMenu ul {
position: absolute;
width: 494px;
padding: 0;
margin: 0;
list-style-type: none;
background: #FFF url(../images/mainMenu_bg.gif) no-repeat;
}
/* float the list to make it horizontal and a relative positon so that you can control the dropdown menu positon */
#mainMenu li {
position: relative;
float: left;
padding-left: 5px;
width: 160px;
vertical-align: middle;
text-align: left;
}
#mainMenu li.center {
padding-left: 0px;
text-align: center;
}
/* style the links for the top level */
#mainMenu a, #mainMenu a:visited {
display: block;
font: bold 12px/1em Helvetica, arial, sans-serif;
color: #FFF;
text-decoration: none;
height: 42px;
line-height: 35px;
}
/* hide the sub levels and give them a positon absolute so that they take up no room */
#mainMenu ul ul {
visibility: hidden;
position: absolute;
height: 0;
top: 35px;
left: -5px;
width: 165px;
}
/* style the table so that it takes no part in the layout - required for IE to work */
#mainMenu table {
position: absolute;
top: 0;
left: 0;
}
/* style the second level links */
#mainMenu ul ul a, #mainMenu ul ul a:visited {
width: 165px;
height: 20px;
line-height: 19px;
font: bold 10px Helvetica, arial, sans-serif;
background: #EF7D0E;
color: #FFF;
text-align: left;
padding: 6px 0 0 5px;
border-top: 1px solid #C1650B;
}
#mainMenu ul ul.last a, #mainMenu ul ul.last a:visited {
width: 162px;
}
/* style the top level hover */
#mainMenu a:hover, #mainMenu ul ul a:hover{
color: #FFF;
text-decoration: underline;
}
#mainMenu :hover > a, #mainMenu ul ul :hover > a {
color: #FFF;
text-decoration: underline;
}
/* make the second level visible when hover on first level list OR link */
#mainMenu ul li:hover ul,
#mainMenu ul a:hover ul{
visibility: visible;
}
我在IE 6中显示表格仍有问题,但我的主要问题是在TOP链接下显示LINK1 ... 6.
我已尝试使用z-index
进行了许多设置,但此处没有任何效果。
我希望你能帮助我;)

试试这个:
div#mainMenu ul
{
position:relative;
z-index:100;
}
