Display a flag using HTML

Back when I was being taught HTML I remember a tag that displayed a little red flag. I've tried everything I can think of and can't find it anywhere. Was I smok开发者_JS百科ing something that day or is there actually a tag for it?

You could in theory do this

<span style="color:red;">&#9873;</span>

but you'll need a Unicode font that supports the Black Flag character.

Maybe ⚐ but it's not a tag nor it's red.

There is no tag for it. See all HTML4 tags.
