因此，如果您想查看我的菜单，请转到here。

因为我知道你需要我的源代码，所以这是HTML：

<div id='menu-container'>
<ul id='menu' class="menu">
   <li class='active'><a href='/'><span>Home</span></a></li>
   <li class='has-sub'><a href='/games/'><span>Games</span></a>
      <ul>
         <li><a href='/games/dota-2/'><span>Dota 2</span></a></li>
         <li><a href='/games/cs-go/'><span>CS: GO</span></a></li>
         <li><a href='/games/css/'><span>CS: Source</span></a></li>
         <li><a href='/games/terraria/'><span>Terraria</span></a></li>
         <li class='last'><a href='/games/minecraft/'><span>Minecraft</span></a></li>
      </ul>
   </li>
   <li class='has-sub'><a href='/about.html'><span>About Us</span></a>
      <ul> 
         <li><a href='http://www.youtube.com/user/'><span>Our YouTube Channel</span></a></li>
         <li><a href='/faq-list.html'><span>Our FAQs/Q&amp;A List</span></a></li>
         <li><a href='/feed-news.rss'><span>Our RSS Feed</span></a></li>
         <li><a href='/wiki/'><span>Our Wiki</span></a></li>
         <li><a href='/wiki/'><span>Our Blog</span></a></li>
                 <li class='last'><a href='/privacy.html'><span>Privacy Policy</span></a></li>
      </ul>
   </li>
   <li class='has-sub last'><a href='/contact.html'><span>Contact Us</span></a>
      <ul>
         <li class='last'><a href='/forums/'><span>Forums</span></a></li>
      </ul>
   </li>
</ul>

这是我的CSS：

这很多，但是如果我不给它你会报告我如何将菜单与我的页面中心对齐（因为我没有编码，这是我的朋友）？我也只想要菜单，没有空的灰色空间。有可能吗？

1 个答案:

答案 0 :(得分：2)

以下是a fiddle，其中介绍了如何将菜单与屏幕中心对齐。您可以通过搜索“已编辑”来搜索我在css中的更改。我用这种方式标记了所有3个变化。

这就是我所做的。

1.删除使整个菜单向左浮动的规则：

#menu-container > ul {
    float: left;
}

2.在他的父元素上指明你想要它在页面的中心：

#menu-container {text-align:center;}

3.然后，对于每个菜单元素，更改以下规则：

#menu-container > ul > li {
    float: left;
}

到

#menu-container > ul > li {
    display: inline-block;
}

至于你的上一个问题（我也只想要菜单，没有空的灰色空间），我不明白你的意思。您想要从菜单栏中删除灰色吗？
