我似乎无法找到任何显示如何扩展列表的信息。我希望它是一个水平类型的导航菜单,每个列表都有一个图像,当你点击图像时,它会展开“span”文本。我希望这是有道理的,并且我没有忽略其他人的问题。
示例:
<ul id="Topics">
<li class="Items">
<img src="results.png" alt="Results">
<span>Title here</span>
<span>Some more text here</span>
</li>
<li class="Items">
<img src="language.png" alt="Language here">
<span>Title here</span>
<span>Some more text here</span>
</li>
<li class="Items">
<img src="wording.png" alt="Wording here">
<span>Title here</span>
<span>Some more text here</span>
</li>
</ul>

这是一个相当奇特的例子:
ul {
text-align: left;
display: inline;
margin: 0;
padding: 15px 4px 17px 0;
list-style: none;
-webkit-box-shadow: 0 0 5px rgba(0, 0, 0, 0.15);
box-shadow: 0 0 5px rgba(0, 0, 0, 0.15);
}
ul li {
font: bold 12px/18px sans-serif;
display: inline-block;
margin-right: -4px;
position: relative;
padding: 15px 20px;
background: #fff;
cursor: pointer;
}
ul li:hover {
background: #555;
color: #fff;
}
ul li ul {
padding: 0;
position: absolute;
top: 48px;
left: 0;
width: 150px;
-webkit-box-shadow: none;
box-shadow: none;
display: none;
opacity: 0;
visibility: hidden;
}
ul li ul li {
background: #555;
display: block;
color: #fff;
text-shadow: 0 -1px 0 #000;
}
ul li ul li:hover { background: #666; }
ul li:hover ul {
display: block;
opacity: 1;
visibility: visible;
}

<ul id="Topics">
<li class="Items">
Title here
<ul>
<li>some more text here</li>
<li>some more text here</li>
</ul>
</li>
<li class="Items">
Title here
<ul>
<li>some more text here</li>
<li>some more text here</li>
</ul>
</li>
<li class="Items">
Title here
<ul>
<li>some more text here</li>
<li>some more text here</li>
</ul>
</li>
</ul>
&#13;
这里的关键代码是这一部分:
ul li:hover ul{
display: block;
opacity: 1;
visibility: visible;
}
基本上,我们在悬停的ul
内选择嵌套的li
。这是有效的,因为:hover
psudo-class与ul
后代相结合,确保我们仅在其父li
悬停时选择此列表。
