【问题描述】：
我需要大约300px 的主菜单和150px 的子菜单。
目前主菜单和子菜单的宽度相同。
我做不到。
有人可以帮忙吗？
我也在此处粘贴代码。
HTML:
<div id='cssmenu'>
<ul>
<li class='active'><a href='index.html'><span>Home</span></a></li>
<li class='has-sub'><a href='#'><span>Products</span></a>
<ul>
<li class='has-sub'><a href='#'><span>Product 1</span></a>
<ul>
<li><a href='#'><span>Sub Item</span></a></li>
<li class='last'><a href='#'><span>Sub Item</span></a></li>
</ul>
</li>
<li class='has-sub'><a href='#'><span>Product 2</span></a>
<ul>
<li><a href='#'><span>Sub Item</span></a></li>
<li class='last'><a href='#'><span>Sub Item</span></a></li>
</ul>
</li>
</ul>
</li>
<li><a href='#'><span>About</span></a></li>
<li class='last'><a href='#'><span>Contact</span></a></li>
</ul>
