使用子菜单时保持菜单按钮的悬停状态

标签: css drop-down-menu

我制作了一个CSS下拉菜单,当您将鼠标悬停在主菜单按钮上时,它会使用hover状态更改背景图片。

但是,如果此人导航到下面的下拉菜单选项,则他们当前处于主菜单按钮会自然失去它的悬停状态。我过去曾使用Javascript来更改类,因此它保留了相同的背景图像,但是想知道有没有办法在没有Javascript的情况下执行它?

HTML:

<div class="navWrapper">
        <div class="left"></div>
        <div class="nav">
            <ul>
                <li class="home"><a href="/">Home</a></li>
                <li class="spacer"></li>
                <li class="about">
                    <a href="about_us/">About Us</a>
                    <ul class="sub">
                        <li><a href="">option 1</a></li>
                    </ul>                        
                </li>
                <!-- About Ends -->

                    </ul>
                    <!-- Sub Ends -->

替换

#header .navWrapper .nav li a:hover,

#header .navWrapper .nav li:hover a,

这是因为您的子菜单是li元素的子项,而不是a标记。

答案 1 :(得分:1)

您应该在父列表项上设置悬停状态的背景图像,而不是链接本身。

/* instead of your */
#header .navWrapper .nav li a:hover

/* try */
#header .navWrapper .nav li:hover a
