我有这个HTML代码:
<div class="cont">
<div class="header">
header
</div><!-- header -->
<div id="cssmenu">
<ul>
<li><a href="#"><span>LINK</span></a></li>
<li><a href="#"><span>LINK</span></a></li>
<li><a href="#"><span>SUB LINK</span></a>
<ul>
<li><a href="#"><span>LINK</span></a></li>
</ul>
</li>
</ul>
</div>
</div><!-- cont -->

随着页面宽度变大,菜单显示在左侧。我怎样才能在标题下始终显示中心?

我想查看标题的CSS;但是,如果你试图让它保持在标题下面,我会创建一个div来围绕标题和菜单,并将属性放到该div中心。
<div class="Container"><!-- Maybe make this class header depending on your css -->
<div class="header">
header
</div><!-- header -->
<div id="cssmenu">
<ul>
<li><a href="#"><span>LINK</span></a></li>
<li><a href="#"><span>LINK</span></a></li>
<li><a href="#"><span>SUB LINK</span></a>
<ul>
<li><a href="#"><span>LINK</span></a></li>
</ul>
</li>
</ul>
</div>
</div> <!-- Close the new div here -->
