我无法使我的 div 的高度匹配。我需要它们使 div 的高度与最多的内容相匹配——这通常很容易，但我正在使用还包含更多文本的叠加层来执行此操作。我不能用固定的高度或宽度来做，因为我需要布局来响应。单元格基本上需要是 col-md-2，文本换行时高度最高，它更像是一个正方形，col-sm-6 是长而窄的，col-xs-12 也是长而狭窄的。
它不一定是 Bootstrap ，但它需要具有这种效果。另一个问题是我需要尽可能多地内联，因为我将它交付给客户以粘贴到他们的 drupal 站点，而无需访问后端，所以请忽略我的粗内联代码。
我几乎明白了，叠加层有效，高度由内容决定，但我无法让高度与最长的相匹配。谁能看出我在这里做错了什么？？

对不起，我很忙，这是一个工作示例:
//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);
});
});.col-xs-4{
border: 1px solid black;
