具有悬停覆盖的等宽+高响应div

时间：2018-03-08 16:36:24

标签： css3 hover overlay responsive equal-heights

我无法在我的div上达到匹配的高度。我需要它们来匹配div的高度和最大的内容 - 这通常很容易但我正在使用包含更多文本的叠加层。我不能用固定的高度或宽度来做，因为我需要布局才能做出响应。细胞需要基本上是col-md-2，最高的高度随着文字的包裹，它更像是一个正方形，col-sm-6会长而窄，col-xs-12也会长狭窄。

它不必是引导程序，但它需要具有这种效果。另一个问题是我需要做尽可能多的内联，因为我将它传递给客户端以粘贴到他们的drupal站点而没有太多访问后端，所以请忽略我粗略的内联代码。

我差不多了，覆盖层工作，高度由内容决定，但我无法达到与最长的匹配。谁能看到我在这里做错了什么？

抱歉，我很忙，这是一个有效的例子：

＆＃13;
＆＃13; 
//we need to iterate through row childs
$('.row').each(function() {
    //Set a var to store the highest height
    var maxHeight = 0;
    //Then, we iterate through all cols inside the row, searching for the highest one.
    $('.col-xs-4', this).each(function() {
        if($(this).height() > maxHeight) {
         maxHeight = $(this).height();  
        }
    });
    //Now, we have the height value of the highest one, so we can apply this height to all row childs.
    $('.col-xs-4', this).each(function() {
        $(this).height(maxHeight); 
     });
});
＆＃13; 
.col-xs-4{
border: 1px solid black;
}
