Bootstrap - I don't want columns to have the same height

Question

In this bootstrap 4 example the 2 columns have the same height. I do not want this. Is there a quick fix for this ?

    <div class="col-lg-3 card bg-faded">
      <h1><small>Some favorites</small></h1>
      <ul>
        <li>Celery root</li>
        <li>Spaghetti Squash</li>
        <li>Killer Mushrooms</li>
      </ul>
    </div>

    <div class="col-lg-9">
      <h1>Wild & Wicky Vegetables</h1>
      <p>Kale c.....t.</p>
    </div>
</div><!--row-->

Answer 1

Bootstrap 5 (update 2021)

Bootstrap 5 is still flexbox based so columns in a row are equal height. Therefore d-block can still be used to "disable" flexbox and use float-start to float columns.

Bootstrap 4 (original answer)

Yes, you can use d-block on the row, and float-left on the columns to make it work the Bootstrap 3.x way with floated columns instead of flexbox..

<div class="row d-block">
    <div class="col-lg-3 float-left">
        ..
    </div>
    <div class="col-lg-9 float-left">
        ..
    </div>
</div>
