如何为所有面板设置固定的引导面板高度？

<div class="col-md-3 padding-0">
  <div class="panel panel-default">
    <div class="panel-body" style="min-height: 10px; max-height: 10px;">
      <img class="img-responsive" src="images/artgram.png" alt="">
      <p>Have you ever been in a company’s reception area that is so impressively stylish that your concept of their professionalism or importance changed for the better? Have you ever been in a company’s reception area that is so impressively stylish that
        your concept of their professionalism or importance changed for the better?</p>
    </div>
  </div>
</div>

<div class="col-md-3 padding-0">
  <div class="panel panel-default">
    <div class="panel-body" style="min-height: 10px; max-height: 10px;">

Answer 1

要么使用固定的height和隐藏的overflow

.panel-body {
    height: 100px;    // or whatever
    overflow: hidden;
}

或者在加载后使用JS动态地将呈现的最大高度分配给所有面板。看我的答案，对于一个非常类似的问题，here。下面复制了这个片段

​

var panels = document.getElementsByClassName('panel-body');

var maxHeight = Array.prototype.map.call(panels, function(panel) {
    return parseInt(getComputedStyle(panel).height, 10);
  })
  .reduce(function(a, b) {
    return Math.max(a, b);
  });

for (var i = panels.length; i-- > 0;) {
  panels[i].style.height = maxHeight + 'px';
}

  <div class="col-md-6">

      <div class="panel-heading">Panel Heading</div>
      <div class="panel-body">Lorem ipsum dolor sit amet, consectetur adipisicing elit.</div>
      <div class="panel-footer">Panel Footer</div>
    </div>
  </div>
  <div class="col-md-6">
    <div class="panel panel-default col">
      <div class="panel-heading">Panel Heading</div>
      <div class="panel-body">

      </div>
      <div class="panel-footer">Panel Footer</div>
    </div>
  </div>
</div>
