Question block in pure CSS

🚧

Whoa there!

This post contains code that's more than 11 years old. It might be fine, but you should probably check to make sure this isn't incredibly stupid by today's standards.

I used a little bit of Sass on this one. I’m trying to think of how a mixin could simplify this, but it seems like it’ll be a lot of manual labor no matter what I do.

I’m not sure what’s up, but something weird is going on with CodePen’s iframe. The animation isn’t working right. It works fine locally and over at CodePen. Oh well.
