以下是我目前的代码。目前注册和加入链接位于左上角。我希望这些位于下拉菜单中。所以在左上角我想要一个下拉菜单，当我将鼠标悬停在菜单上时，这两个链接会出现在那里，当我单击它们时，相同的弹出窗口会出现在屏幕中间。

最佳答案

这应该很容易做到。用这个替换 header-links div 中的代码。HTML:

<ul>
    <li><a href="#">Dropdown</a>
        <ul>
            <li><a href="#" onclick="signin()">Sign In</a></li>
            <li><a href="#" onclick="join()">Join</a></li>
        </ul>
    </li>
</ul>

并将其添加到您的 css 类中

CSS:

ul ul {
    display: none;
}

ul li:hover > ul {
    display: block;
}

我还建议您删除 .header-links 类中的负边距，并将 float:left 添加到您的 #header-img-wrap.

希望对您有所帮助。
