</html>我想在我的 JSP 页面中显示我的 href 链接的父子树流，在谷歌搜索了一段时间后我知道它可以通过 CSS 完成。 我指的是这个网站：http://thecodeplayer.com/walkthrough/css3-family-tree
但是，即使复制了相同的代码，它似乎在我的页面中也不起作用。
HTML：
<div class="tree" id="tree">
<ul>
<li>
<a href="#">Parent</a>
<ul>
<li>
<a href="#">Child</a>
<ul>
<li>
<a href="#">Grand Child</a>
</li>
</ul>
</li>
<li>
<a href="#">Child</a>
<ul>
<li><a href="#">Grand Child</a></li>
<li>
<a href="#">Grand Child</a>
<ul>
<li>
<a href="#">Great Grand Child</a>
</li>
<li>
<a href="#">Great Grand Child</a>
</li>
<li>
<a href="#">Great Grand Child</a>
</li>
</ul>
</li>
<li><a href="#">Grand Child</a></li>
</ul>
</li>
</ul>
</li>
</ul>
CSS：
* {margin: 0; padding: 0;}
.tree ul {
padding-top: 20px; position: relative;
-transition: all 0.5s;
-webkit-transition: all 0.5s;

/*We need to remove left-right connectors from elements without
any siblings*/

/*Remove left connector from first child and
right connector from last child*/
.tree li:first-child::before, .tree li:last-child::after{

【问题讨论】：
-
在这里工作：jsfiddle.net/xba35b9L 你能指定什么在你的页面上不起作用吗？
-
我只是尝试了一个简单的 HTML 页面，它正在工作，但是当作为 JSP 页面运行时，相同的代码我只能看到一个列表（附上屏幕截图）
-
表示JSP页面中的CSS引用错误。它没有应用 CSS。发布 JSP 代码。
-
发布了JSP代码，我指的是同一个页面中其他一些样式的同一张表，效果很好
-
可能是缓存问题？有它的演示页面吗？
