html - 使列高度填充行 bootstrap 4

我的页面上有一排带有一些列的行。这些包含的卡在内容量上略有不同。但我希望这些高度都相同。

        <p></p>
        <a href="" class="btn btn-info"><i class="zmdi zmdi-

  <div class="col-md-3 ">
    <div class="card">

      <div class="card-body overflow-hidden text-center">
        <h4 class="color-primary">card 1</h4>
        <p></p>
        <a href="" class="btn btn-info"><i class="zmdi zmdi-
       download"></i>download</a>
      </div>
    </div>
  </div>
  <div class="col-md-3 ">
    <div class="card">
      <img src="image1.jpg" class="img-fluid" alt="" />
      <div class="card-body overflow-hidden text-center">
        <h4 class="color-primary">card 1</h4>
        <p></p>
        <a href="" class="btn btn-info"><i class="zmdi zmdi-
            download"></i>download</a>
      </div>
    </div>
  </div>
</div>

如您所见，我尝试了内容拉伸和项目拉伸。两者都不起作用。
