Missing closing tags

[Baribj]

On the example: https://javascript.info/event-delegation#behavior-counter

Counter: <input type="button" value="1" data-counter>
One more counter: <input type="button" value="2" data-counter>

No closing tags. They don't throw an error because browser will fix them, but I think they should be fixed none the less.

Counter: <input type="button" value="1" data-counter />
One more counter: <input type="button" value="2" data-counter />
