  <h2>Card Group</h2>
  <p>The .card-group class is similar to .card-deck, which creates an <strong>equal height and width</strong> grid of cards.</p>
  <p>However, the .card-group class removes left and right margins between each card.</p>
  <p>In this example we have added extra content to the first card, to make it taller. Notice how the other cards follow.</p>
  <p><strong>Note:</strong> The cards are displayed vertically on small screens (less than 576px), <strong>WITH</strong> top and bottom margin:</p>
  <div class="card-group">
    <div class="card bg-primary">
      <div class="card-body text-center">
        <p class="card-text">Some text inside the first card</p>
        <p class="card-text">Some more text to increase the height</p>
        <p class="card-text">Some more text to increase the height</p>
        <p class="card-text">Some more text to increase the height</p>
      </div>
    </div>
    <div class="card bg-warning">
      <div class="card-body text-center">
        <p class="card-text">Some text inside the second card</p>
      </div>
    </div>
    <div class="card bg-success">
      <div class="card-body text-center">
        <p class="card-text">Some text inside the third card</p>
      </div>
    </div>
    <div class="card bg-danger">
      <div class="card-body text-center">
        <p class="card-text">Some text inside the fourth card</p>
