<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>
