Heads up! This blog post hasn't been updated in over 2 years. CodePen is an ever changing place, so if this post references features, you're probably better off checking the docs. Get in touch with support if you have further questions.

Have you noticed the Daily UI Pens popping up in the Picks lately? They're inspired by Daily UI, an email-a-day challenge for designers to create UI elements — landing pages, forms of all kinds, 404 pages, and a whole lot more.

I first noticed these popping up in Recent Pens near the end of last year, but they're really picking up steam now. Check out a few of my favorites!

Fabio Ottaviani is up to day 22 as I write this. He's turning out gems like this slick credit card checkout form.

I'm fond of fun 404 pages (I love to collect them), so naturally I like Dominic Magnifico's 404 page for the truly Lost.

Maybe if my inbox had Pavel Laptev's delightfully animated app icon, I wouldn't feel so bad that I can never get it down to zero.

No one can be uncheered with a balloon, so of course I have to smile when I see Star St.Germain's charming landing page 🎈
