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

时间：2015-06-28 11:52:46

标签： html css drop-down-menu menu css-selectors

我有一个带有此CSS的HTML / CSS菜单，用于活动链接：

 $lienphoto = "adresse sur serveur".$nomimage;

$data = str_replace('data:image/jpg;base64,', '', $image);

$data = str_replace(' ', '+', $data);

$data = base64_decode($data);

$success = file_put_contents($lienphoto, $data);

如果顶级父链接中的任何子链接或其子链接具有活动类，如何将其设置为活动链接？

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;
    color: #4d4d4d;
    text-decoration: none;
    display: inline-block;
    margin-bottom: 0;
    text-transform: uppercase;
    border-bottom: 2px solid #fff;
    -webkit-transition: background-color .2s linear, padding-top .2s linear;
    -moz-transition: background-color .2s linear, padding-top .2s linear;
    -o-transition: background-color .2s linear, padding-top .2s linear;
    -ms-transition: background-color .2s linear, padding-top .2s linear;
    transition: background-color .2s linear, padding-top .2s linear;
}
.navigation ul li a:hover,.navigation ul li:hover,.navigation .active-nav {
    background-color: #F36F25; /*#373737;*/
    text-shadow: none;
    color: #f7f7f7!important;

    box-shadow: 0 3px 0 #ff8833;
}

这是一个纯CSS解决方案，使用:hover状态并重新使用它。

  • 在这里，你应用你想要的风格:hover状态：
li:hover a {
  color: orange;
  font-weight: 700
}
  • 现在，您可以阻止li儿童徘徊在
    • 上 
li:hover li a {
  color: none;
  font-weight: 400
}

最后，您为:hover孩子

重新执行li州 
li:hover li:hover a {
  color: orange;
  font-weight: 700
}

这是一个片段:(这只是一个工作演示，我只使用了您的HTML代码）

＆＃13;
＆＃13; 
li:hover a {
  color: orange;
  font-weight: 700
}
li:hover li a {
  color: none;
  font-weight: 400
}
li:hover li:hover a {
  color: orange;
  font-weight: 700
}

答案 2 :(得分：6)

您可以使用选择器.navigation li:hover > a设置当前处于活动状态的菜单项 AND 其所有祖先菜单项（父级，祖父级，...）。

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。

答案 3 :(得分：5)

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');
});

答案 4 :(得分：1)

截至目前（2015年），仅使用CSS无法做到这一点。 但是，您可以使用Jquery执行此操作。 $("a.active").parents('li').css("property", "value");
