Do you need to close meta and link tags in HTML?

Question

I was just reading somebody\'s HTML who never closed meta and link tags in the HTML head section. The code worked fine; is closing these tags optional?

I thought it

Answer 1

It depends on the doctype. HTML5 doesn't need the closing. XHTML does.

In HTML5, so-called void elements (elements that can't have content) don't need the closing, as they are self-closing. But it is still valid if you close them..
