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.

A floated button group and a floated search field share one toolbar row.
A quote floated to the end of the paragraph; the article wrapper is cleared so the next section starts below.
"We make good brands great"
We listen first, then build a plan around what you actually need. We measure success by how many clients come back and tell their friends. Small teams, short feedback loops and no handoffs lost in translation. Every project starts with a workshop, so we understand your audience before we design.
Fixed prices and weekly demos keep you in control from start to finish.
