目前,即使我在#menu li li a 中将其指定为文本对齐中心,我在子菜单中的添加主题、删除主题、删除主题、手动抓取也没有集中。子菜单的执行摘要也被切断。我可以知道如何扩展子菜单并集中所有文本吗?谢谢!
这是我的代码(我真的很抱歉,因为我没有 jsfiddle 帐户并且在等待名单上):
HTML
<div id="menu">
<ul>
<li><a href="#" >Home</a></li>
<li><a href="#" >Executive Summary</a></li>
<li><a href="#" > Visual Analytics</a></li>
<li><a href="#" >Settings</a>
<ul>
<li><a href="#">Add Subject</a></li>
<li><a href="#">Delete Subject</a></li>
<li><a href="#"> Edit Subject</a></li>
<li><a href="#" >Manual Crawl</a></li>
<li><a href="#" >Executive Summary</a></li>
</ul>
</li>
</ul>
