Blown up by CSS

Nostalgia, curiosity, and amazement all came flowing in when I saw this CodePen by Bali Balo of a Pure CSS Minesweeper game! And I mean PURE CSS!

That's right! You can play the awesome classic from Windows past, right in your browser without any javascript needed! Complete with Windows XP background as well (nice touch).

This unfortunately makes me realize I have much to learn still about CSS which can create some wonders out there for sure! If I get some time I'll have to try to rip this apart to see how it ticks.
