css bootstrap make all cols in row same height [duplicate]

Question

I have two boxes next to each other, Box1 (left) has a little text and Box2 (right) has alot of text:

How can I make Box 1 extend to be the same height as Box 2 by padding more white space onto box 1? I'm trying to make it so both boxes are the same height; my code looks like this:

<div class="container-fluid">
  <div class="row">
    
    <div class="col-md-4">
      <div class="card mb-4 box-shadow">
        <!-- BOX1 -->
        <div class="card-body">
          box 1 data here   
        </div> 
       </div>
      </div> <!-- /col -->
    

    <div class="col-md-8">
      <div class="card mb-4 box-shadow">
        <!-- BOX2 -->
        <div class="card-body">
          box 2 data here   
          box 2 data here 
          box 2 data here 
        </div> 
       </div>
      </div> <!-- /col -->
    
  </div> <!-- /row -->
</div>
