我有一个下拉菜单出现在我的图像转换库 div 后面。下面是它的外观及其 HTML 和 CSS 的图像。

enter image description here

HTML:

<body>
<div id="top_bar">
<div id="top_inner">
<div id="logo"> <a href="http://www.edosbornephotography.com"><img src="images/logo.gif" alt="Ed Osborne" width="225" height="115" class="logo"></a></div>
<div class="nav">
<ul class = "menu" >
<li> <a href = "#" > Home </a> </li>
<li><a href = "#" > Packages </a>
<li><a href = "#" > Weddings </a>
<li><a href = "#" id="left" > Lifestyle </a>
<ul class = "submenu" >
<li> <a href = "#" > Families </a> </li>
<li> <a href = "#"> Newborn/Child </a> </li>
<li> <a href = "#" > Portraits </a> </li>
</ul>
</li>

<li> <a href = "#" > Blog </a> </li>
<li><a href = "#" id="left"> Abous Us </a>
<ul class = "submenu" >
<li> <a href = "#" > Ed Osborne </a> </li>
<li> <a href = "#" > Testimonials </a> </li>
<li> <a href = "#" > FAQs </a> </li>
</ul>
</li>

<li> <a href = "#" > Contact Us </a> </li>
<li> <a href = "#" > Links </a> </li>
</ul>
</div>
</div>
</div>

<div id="main">

<div id="smart-gallery">
<a href="images/cubagallery-img-1.jpg">
<img src="images/cubagallery-img-1.jpg" /></a>

<a href="images/cubagallery-img-15.jpg">
<img src="images/cubagallery-img-15.jpg" /></a>

<a href="images/cubagallery-img-3.jpg">

<a href="images/cubagallery-img-4.jpg"></a>
<img src="images/cubagallery-img-4.jpg" /></a>
</div>

</div>

CSS:

.min-gallery
{
width: 927px;
height: 615px;
border: solid 1px black;
background-color: Black;
background: url(../images/bg.jpg);
margin: auto;
margin-left: 232px;
}

.min-gallery .preview
{
width: 852px;
height: 493px;
margin-top: 36px;
margin-left: 36px;
margin-right: 36px;
position: relative;
border: solid 2px black;
overflow: hidden;
background-color: White;
}

.min-gallery .preview img
{
/* width: 795px; height: 525px;*/
position: absolute;
}

.min-gallery .bottom
{
width: 100%;
height: 98px;
color: Gray;
font-family: Arial;
font-size: 1em;
font-weight: bold;
overflow: hidden;
}

#top_bar {
width: 100%;
height: 145px;
background: #000000;
padding-bottom: 20px;
}

#top_inner {
text-align: center;
margin: 0 auto;
width: 1000px;
height: 144px;
}

.nav {
margin: 0 auto;
position: relative;
padding-top: 100px;
}

ul.menu {
list-style: none;
margin: 0;
float: left;
background: #222;
font-size: 1.2em;
background: url(../images/topnav_bg.gif) repeat-x;
}
ul.menu li {
float: left;
margin: 0;
position: relative;
}
ul.menu li a{
padding: 10px 18px;
color: #fff;
display: block;
text-decoration: none;
float: left;
}

ul.menu li a#left{
padding: 10px 5px;
color: #fff;
display: block;
text-decoration: none;
float: left;
}

ul.menu li a:hover {
background: url(../images/topnav_hover.gif) no-repeat center top;
}

ul.menu li span {
width: 11px;
height: 35px;
float: left;
background: url(../images/subnav_btn.gif) no-repeat center top;
}

ul.menu li span.subhover {
background-position: center bottom; cursor: pointer;
}

ul.menu li ul.submenu {
list-style: none;
position: absolute;
left: 0; top: 35px;
background: #333;
margin: 0; padding: 0;
display: none;
float: left;
width: 170px;
-moz-border-radius-bottomleft: 5px;
-moz-border-radius-bottomright: 5px;
-webkit-border-bottom-left-radius: 5px;
-webkit-border-bottom-right-radius: 5px;
border: 1px solid #111;
}

ul.menu li ul.submenu li{
margin: 0; padding: 0;
border-top: 1px solid #252525;
border-bottom: 1px solid #444;
clear: both;
width: 170px;
}

html ul.menu li ul.submenu li a {
float: left;
width: 122px;
padding-left: 30px;
text-align: left;
}

当我从 .min-gallery .preview img 中删除 position:absolute 时,下拉菜单出现在顶部,这是我想要的,但图像确实停止变化,只停留在一张图像上。

有人有快速解决办法吗?很抱歉粘贴了所有代码,但我不知道我还能如何向你们表达我的观点

谢谢

最佳答案

设置下拉菜单的较高z-index。

.submenu { z-index: 999; }

原因“具有较高堆栈顺序的元素始终位于具有较低堆栈顺序的元素之前。”
