两个元素同时悬停

Question

查看随附的jsfiddle：

http://jsfiddle.net/muncherelli/dLsgokva/

我有三个不同的链接：相关文本链接，相关图像链接和不相关的文本链接。相关链接转到一个网址，不相关的链接转到另一个网址。

如果您当前将鼠标悬停在单个三个元素上，则每个元素都将自行悬停。我希望相关图像和相关链接都可以在其中任何一个悬停时进入“悬停”状态。当您将鼠标悬停在除了不相关的链接之外的任何其他内容时，不相关的链接不应悬停。是否有原生的CSS方式来做到这一点？我也有jQuery可供使用。

请注意，一个页面上会有多个这样的容器，每个容器都有不同的URL。他们需要能够独立工作，因为他们会去不同的链接。

这是我的HTML：

<div class="container rounded-bg">
    <a href="#related-url"><img src="http://placehold.it/400x300?text=.related-img" class="related-img effects rounded" />
    <div class="content">
        <div class="content-top">
            <a href="#unrelated-url" class="unrelated effects">Unrelated Link</a>
        </div>
        <div class="content-bottom">
            <a href="#related-url" class="related effects"><h1>Related Link</h1></a>
        </div>
    </div>
</div>
<br /><br />
<div class="container rounded-bg">
    <a href="#related-url"><img src="http://placehold.it/400x300?text=.related-img" class="related-img effects rounded" />
    <div class="content">
        <div class="content-top">
            <a href="#unrelated-url" class="unrelated effects">Unrelated Link</a>
        </div>
        <div class="content-bottom">
            <a href="#related-url" class="related effects"><h1>Related Link</h1></a>
        </div>
    </div>
</div>
<br /><br />
<div class="container rounded-bg">
    <a href="#related-url"><img src="http://placehold.it/400x300?text=.related-img" class="related-img effects rounded" />
    <div class="content">
        <div class="content-top">
            <a href="#unrelated-url" class="unrelated effects">Unrelated Link</a>
        </div>
        <div class="content-bottom">
            <a href="#related-url" class="related effects"><h1>Related Link</h1></a>
        </div>
    </div>
</div>
<br /><br />
<div class="container rounded-bg">
    <a href="#related-url"><img src="http://placehold.it/400x300?text=.related-img" class="related-img effects rounded" />
    <div class="content">
        <div class="content-top">

            <a href="#related-url" class="related effects"><h1>Related Link</h1></a>
        </div>
    </div>
</div>

我的CSS：

div.content {

div.content-top {

    right: 20px;
    top: 20px;

div.content-top {

div.content-bottom {

我不确定它是否可以在纯CSS中使用，因为CSS没有父选择器。假设您的标记可以接受jQuery解决方案，这将有效:(请注意对CSS .related-img.active和.related.active的更改

$('.container').on('mouseenter', '.related, .related-img', function(){
    $link = $(this).closest('.container').find('.related, .related-img').addClass('active');
});
$('.container').on('mouseleave', '.related, .related-img', function(){
    $link = $(this).closest('.container').find('.related, .related-img').removeClass('active');
});

body {
    font-family: sans-serif;
