如果使用CSS激活子级或孙级链接,则将父级链接设置为活动状态

Question

如果使用CSS激活子级或孙级链接,则将父级链接设置为活动状态

cha*_*lie 18 html css menu css-selectors drop-down-menu

我有一个HTML/CSS菜单,其中包含用于活动链接的CSS:

.navigation ul li a:hover, .navigation .active-nav {
    background-color: #F36F25; /*#373737;*/
    text-shadow: none;
    color: #f7f7f7 !important;
    -webkit-box-shadow: 0 3px 0 #ff8833;
    box-shadow: 0 3px 0 #ff8833;
}

将样式添加到li元素:http://jsfiddle.net/kyvbzssd/3/

.navigation ul li{
    padding: 80px 9px 10px;
}
.navigation ul li a,.navigation ul li{
    font-size: 13px;
    font-weight: 700;

这是一个使用:hover状态并再次重用的纯CSS解决方案.

在这里,你应用你想要的风格:hover:

li:hover a {
  color: orange;
  font-weight: 700
}

现在你可以防止li孩子们徘徊

li:hover li a {
  color: none;
  font-weight: 400
}

最后,你重新:hover为li孩子们做了这个州

li:hover li:hover a {

}

您可以使用选择器.navigation li:hover > a设置当前活动的菜单项及其所有祖先菜单项(父级,祖父级,...)的样式.

我将此添加到您的演示中,删除了未使用的样式,优化了选择器并进行了其他一些改进.

您可以在下面的JSFiddle和代码段中找到结果.

只有通过CSS才有可能.你应该使用一些JavaScript代码.

$('.child').on('click', function(){
   $(this).closest('.parent').toggleClass('active');
});
