Question

嗨，我有这个导航栏，并想知道如何将它向右下方。我试过漂浮：对，但不起作用。也试过div对齐但不工作同样。我虽然是css的新手。

<div align="right">
        <ul id="menu">
            <li><a href="#">Home</a></li>
            <li>
              <a href="#">About ￬</a>
              <ul class="hidden">
                <li><a href="#">Who We Are</a></li>
                <li><a href="#">What We Do</a></li>
              </ul>
            </li>
        </ul>
</div>

        min-width: 100px;
        padding: 0 20px;

Answer 1

align="right" attribute is deprecated。不要用它！

删除ul元素上的绝对定位，然后将元素向右浮动or add right: 0。

<div>
  <ul id="menu">
    <li><a href="#">Home</a></li>

        <li><a href="#">Who We Are</a></li>
        <li><a href="#">What We Do</a></li>
      </ul>
    </li>
  </ul>
</div>

ul {
    list-style-type: none;
    margin: 0;
    padding: 0;
    float: right;

找到我的立场答案：相对而非绝对

Answer 3

你需要添加＆＃34;宽度：100％和＃34;在文件css中。代码：

ul {
        list-style-type:none;
        margin:0;
        padding:0;
        position: absolute;
        width: 100%;
}

将导航栏对齐到右侧
