我有一个水平导航菜单,当您将鼠标悬停在菜单上时,这些项目会显示在网页上的图像后面而不是前面。我该如何解决这个问题?
HTML:
<div id="nav">
<ul>
<li><a href="#">Home</a></li>
<li><a href="#">Tutorials</a>
<ul>
<li><a href="#">Photoshop</a></li>
<li><a href="#">Illustrator</a></li>
<li><a href="#">Web Design</a>
<ul>
<li><a href="#">HTML</a></li>
<li><a href="#">CSS</a></li>
</ul>
</li>
</ul>
</li>
<li><a href="#">Articles</a>
<ul>
<li><a href="#">Web Design</a></li>
<li><a href="#">User Experience</a></li>
</ul>
</li>
<li><a href="#">Inspiration</a></li>
</ul>
</div>
CSS:
#nav ul ul {
display: none;
}
#nav ul li:hover > ul {
display: block;
}
#nav ul {
background: #efefef;
background: linear-gradient(top, #efefef 0%, #bbbbbb 100%);
background: -moz-linear-gradient(top, #efefef 0%, #bbbbbb 100%);
background: -webkit-linear-gradient(top, #efefef 0%,#bbbbbb 100%);
box-shadow: 0px 0px 9px rgba(0,0,0,0.15);
padding: 0 20px;
border-radius: 10px;
list-style: none;
position: relative;
display: inline-table;
}
#nav ul:after {
content: ""; clear: both; display: block;
}
#nav ul li {
float: left;
}
#nav ul li:hover {
background: #4b545f;
background: linear-gradient(top, #4f5964 0%, #5f6975 40%);

background: -webkit-linear-gradient(top, #4f5964 0%,#5f6975 40%);
}
#nav ul li:hover a {
color: #fff;
}
#nav ul li a {
display: block; padding: 25px 40px;
color: #757575; text-decoration: none;
}
#nav ul ul {
background: #5f6975; border-radius: 0px; padding: 0;

#nav ul ul li a:hover {

}

您应该尝试使用z-index css属性:
.horizontalmenu{
z-index:10; /*or more than your image */
position:relative;
}
如果您想要更准确的答案,请发布一些代码
编辑:正如Don在评论中所说,请确保将您的菜单放在适当的位置:relative(编辑过的css)

只需设置z-index=1
(或任何高于图像的数字),例如在菜单的css中。希望这会有所帮助:)
