A clearfix makes a parent element wrap around its floated children again, so borders, backgrounds and the content that follows stay where you expect. The examples outline every parent with a dashed border and every floated box with a solid one, so you can see the helper at work.
1Two floated buttons
The parent wraps a float-start and a float-end button, so its dashed border surrounds both.
Dashed border: the .clearfix parent. It keeps its height even though both children float.
<div class="hp-cf clearfix">
<button type="button" class="btn btn-outline-secondary float-start">Back</button>
<button type="button" class="btn btn-primary float-end">Continue</button>
</div>
<p class="small text-body-secondary mt-2 mb-0">Dashed border: the .clearfix parent. It keeps its height even though both children float.</p>
2With and without clearfix
Side by side comparison: without the helper the parent collapses to its padding and the float hangs out.
A title floated left and a status badge floated right inside a card header.
