Not so much as a problem but I was wondering why some input tags in HTML have a "/" at that end while others do not.
Ex:
<input name="username" id="username" />

The HTML5 spec calls these [void elements](https://html.spec.whatwg.org/multipage/syntax.html#void-elements) and they represent elements that cannot have any contents – Hunter McMillen Apr 10 '20 at 01:09
