Auto-size dynamic text to fill fixed size container
How can I get this text to shrink/enlarge the font-size automatically to fit perfectly wrapped into the box size?
I’m trying to do this with HTML & CSS but I don’t see any option. I don’t mind using javascript/jquery if there is a way.

Something like this maybe?

Edit: Of course someone had already come up with a better solution… Check out the link in John’s comment, has some good solutions! Still, it was good fun to have a crack at it! 🙂
