How to Achieve Equal Heights for Cards in Bootstrap 4 Columns?

Equaling the Heights of Bootstrap 4 Cards in Columns

As mentioned, the Bootstrap 4 framework already implements flexbox on columns, which ensures they are initially of the same height. To achieve equal card heights within these columns, consider using the h-100 class on the cards. This class sets the height to 100%, enabling the cards to fully occupy the available space within each column.

Here's an example of how to implement this using h-100:

<code class="html"><div class="container">
    <div class="row">
        <div class="col-md-4 col-sm-6 col-12">
            <div class="card h-100">
                ...
            </div>
        </div>
        <div class="col-md-4 col-sm-6 col-12">
            <div class="card h-100">
                ...
            </div>
        </div>
        <div class="col-md-4 col-sm-6 col-12">
            <div class="card h-100">
                ...
            </div>
        </div>
    </div>
</div></code>

This modification ensures that the cards within each column will be of equal height, regardless of their content. It's important to note that the .card-deck class, which previously contained the cards, is no longer necessary.
