用水平 css 菜单填充表格单元格

Question

我有一个包含在 div 中的 css 菜单（我下载的源代码，因为我对 css 不了解）

<div id='cssmenu' style='float:right;'>
  <ul>
    <li id='index'><a href='index.php'><span>Home</span></a></li>
    <li id='aboutus'><a href='aboutus.php'><span>About Us</span></a></li>
    <li id='gallery'><a href='gallery.php'><span>Galley</span></a></li>
    <li id='videos'><a href='videos.php'><span>Videos</span></a></li>
    <li id='links'><a href='links.php'><span>Links</span></a></li>
    <li id='contact'><a href='contact.php'><span>Contact</span></a></li>
  </ul>
</div>

我在 <td> 内部有一个固定宽度（为简单起见，假设为 500 像素）。我调整了css中的填充以使宽度很好地适应……至少在Firefox中。当我在 Chrome 中查看它时，最后一个菜单项超出了表格单元格的宽度，最终位于菜单其余部分的下方。

我的问题是，如何使菜单项在表格宽度上等距分布？将 padding 设置为 0px 会使所有东西看起来都很小而且被压扁，我仍然想要垂直填充。

这是我的 css（对不起，我知道它很长）

Answer 1

如果你使用 table 会很容易，但是这里你有 ul 所以我建议你使用 calc() 函数，如果你能接受的话。或等待其他解决方案。我已经用你的代码测试了它，比如 width: calc(100%/ 6);而且效果很好。

我已将此规则添加到#cssmenu ul li

Answer 2

试试这个

ul{
display:table;
table-layout: fixed;
width: 100%;
}
li{
    display:table-cell;
    display: table-cell;
    float: none;
}

我希望它有效。
