Clear:both question

I understand why we're applying clear: both to a parent element whose child-divs cause its height to collapse, but why is the clear:both grouped with other properties like this (with 'content' and 'display')?

.group:after { content: ""; display: table; clear: both;

}

Also what does the pseudo class :after do?

Thank you! Stephanie

My understanding is it creates a "fake" child element for the class you're working on. This way it auto clears the float from anything following it: https://developer.mozilla.org/en-US/docs/Web/CSS/::after

Also commonly referred to as a 'clearfix'.
