正如标题所说，我正在尝试将菜单移动到边框菜单内。我对此很陌生，因为它们在理论上是链接，所以我认为它会是这样的。 a { position:absolute 然后我会选择我想让他们去的地方。最重要的是，我还需要移动一个子菜单。有任何想法吗？谢谢!我想将菜单移动到边框内的右下角。

最佳答案

您的 CSS 的问题在于您的选择器，您一直将 #navigation 放在不应该去的地方，这会破坏您的 CSS。例如，你的 li 规则是这样的:

ul #navigation li {
    border: 1px solid #89cFF0;
    width: 125px;
    text-align: center;
    position: relative;
    float: left;
    list-style-type: none;
}

HTML 是这样的:

<ul id="navigation">
        <li><a href="index.html">Home</a></li>
        <li><a href="videos.html">Videos</a>
            <ul class="sub">
                <li><a href="vines.html">Vines</a></li>
                <li><a href="#">Pugs</a></li>
                <li><a href="#">Failing Dogs</a></li>
                <li><a href="#">Crazy Dogs</a></li>
                <li><a href="#">Funny Dogs</a></li>

            </ul>
        </li>


        <li><a href="#">Photographs</a></li>    
        <li><a href="#">Articles</a></li>
        <li><a href="#">Contact</a></li>
    </ul>

您的 CSS 正在尝试为 <li> 设置样式这是#navigation 的子项，它是<ul> 的子项，因为 ul 是#navigation，所以没有。您应该这样选择它:

#navigation li {
    border: 1px solid #89cFF0;
    width: 125px;
    text-align: center;
    float: left;
    list-style-type: none;
}
