How to create a grid of Bootstrap 4 cards of equal height and width?

Cover image

There are two different options if you want to create equal height cards using Bootstrap 4.

Card Groups

Use card groups to render cards as a single, attached element with equal width and height columns. Card groups start off stacked and use display: flex; to become attached with uniform dimensions starting at the sm breakpoint.

<div class="card-group">
  <div class="card">
    <svg class="bd-placeholder-img card-img-top" width="100%" height="180" xmlns="http://www.w3.org/2000/svg" preserveAspectRatio="xMidYMid slice" focusable="false" role="img" aria-label="Placeholder: Image cap"><title>Placeholder</title><rect width="100%" height="100%" fill="#868e96"></rect><text x="50%" y="50%" fill="#dee2e6" dy=".3em">Image cap</text></svg>
    <div class="card-body">
      <h5 class="card-title">Card title</h5>
      <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This content is a little bit longer.</p>
      <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
    </div>
  </div>
  <div class="card">
    <svg class="bd-placeholder-img card-img-top" width="100%" height="180" xmlns="http://www.w3.org/2000/svg" preserveAspectRatio="xMidYMid slice" focusable="false" role="img" aria-label="Placeholder: Image cap"><title>Placeholder</title><rect width="100%" height="100%" fill="#868e96"></rect><text x="50%" y="50%" fill="#dee2e6" dy=".3em">Image cap</text></svg>
    <div class="card-body">
      <h5 class="card-title">Card title</h5>
      <p class="card-text">This card has supporting text below as a natural lead-in to additional content.</p>
      <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
    </div>
  </div>
  <div class="card">
    <svg class="bd-placeholder-img card-img-top" width="100%" height="180" xmlns="http://www.w3.org/2000/svg" preserveAspectRatio="xMidYMid slice" focusable="false" role="img" aria-label="Placeholder: Image cap"><title>Placeholder</title><rect width="100%" height="100%" fill="#868e96"></rect><text x="50%" y="50%" fill="#dee2e6" dy=".3em">Image cap</text></svg>
    <div class="card-body">
      <h5 class="card-title">Card title</h5>
      <p class="card-text">This is a wider card with supporting text below as a natural lead-in to additional content. This card has even longer content than the first to show that equal height action.</p>
      <p class="card-text"><small class="text-muted">Last updated 3 mins ago</small></p>
    </div>
  </div>
