How to Make Bootstrap 4 Card-Columns Cards of Equal Height?

Making Bootstrap Cards of Equal Height in Card-Columns

In Bootstrap 4, the card-columns class is used to display cards in columns, but cards may vary in height depending on their content. To achieve equal height cards, we can use a combination of CSS and flexbox.

Solution:

Instead of setting a fixed minimum height on the cards, we can use the align-items-stretch utility on the column elements within the card-columns. This makes the columns stretch to the full height of the tallest card.

.card-columns .col {
    align-items: stretch;
}

Implementation:

Wrap your card-columns within a container and each card within a column as follows:

<div class="container">
    <div class="row">
        <div class="col-lg-4 align-items-stretch">
            <div class="card">
                <!-- Card content -->
            </div>
        </div>
        <div class="col-lg-4 align-items-stretch">
            <div class="card">
                <!-- Card content -->
            </div>
        </div>
        <div class="col-lg-4 align-items-stretch">
            <div class="card">
                <!-- Card content -->
            </div>
        </div>
    </div>
</div>

Note:

• Ensure that the column widths (col-lg-4 in this example) are equal for all columns.
• If there are any background or borders on the cards, you may need to adjust the CSS to ensure the borders and backgrounds align correctly.
