How do auto-layout grid columns work compared to fixed breakpoints?

Asked on Jun 07, 2025

In Bootstrap 5, auto-layout grid columns allow you to create flexible layouts without specifying exact column sizes, unlike fixed breakpoints which require specific column widths. Auto-layout columns automatically adjust based on the content and available space.

<!-- BEGIN COPY / PASTE -->
        <div class="container">
            <div class="row">
                <div class="col">Auto-layout column</div>
                <div class="col">Auto-layout column</div>
            </div>
            <div class="row">
                <div class="col-6">Fixed column</div>
                <div class="col">Auto-layout column</div>
            </div>
        </div>
        <!-- END COPY / PASTE -->

Additional Comment:

Auto-layout columns (`col`) automatically distribute space equally among themselves.
Fixed columns (`col-6`) take up a specific portion of the grid (e.g., 6 out of 12), with remaining space distributed among auto-layout columns.
Auto-layout is useful for responsive designs where content size may vary.
