Make sure the element clears its child elements. This is useful only if you are still using floats to build your layout. Consider using a modern approach with a flexible box layout or grid layout.
HTML CODE
<div class="clearfix">
<div class="floated">
float a
</div>
<div class="floated">float b</div>
</div>
CSS CODE:
.clearfix::after {
content: '';
display: block;
clear: both;
}
.floated {
float: left;
}
