html - 浏览器在代码中没有空格的地方放置空格

Question

为什么以下标记在每个 <li></li> 之后产生一个空格, 当源代码中没有空格时？如果我将它们全部放在一行中，则在预览页面时空格会消失。但为什么浏览器将我的制表符读取为空格？

(您可以在第一张图片左侧的服务旁边看到一个边框。边框和服务之间是空格。图片 2 中没有。)

<nav>
    <ul>
        <li><a href="#" class="active">HOME</a></li>
        <li><a href="#">SERVICES</a></li>
        <li><a href="#">PRODUCTS</a></li>
        <li><a href="#">ABOUT</a></li>
        <li><a href="#">CONTACT</a></li>
        <li><a href="#">LIKE US</a></li>
    </ul>
</nav>

这是移除了所有标签的情况:

<nav>
    <ul>
        <li><a href="#" class="active">HOME</a></li><li><a href="#">SERVICES</a></li><li><a href="#">PRODUCTS</a></li><li><a href="#">ABOUT</a></li><li><a href="#">CONTACT</a></li><li><a href="#">LIKE US</a></li>
    </ul>
</nav>

编辑:

浏览器是 OSX Lion 上的 Safari 5.1.5。编辑是 Espresso。还尝试了 TextMate。这是导航的 CSS。

Answer 1

将 li 的显示更改为 display:table-cell 而不是 display:inline-block。
