Stripe Elements: Pre-built UI components to help you create checkout flows
Stripe front end developers are a true inspiration. I know the linked project isn't anything revolutionary, but as someone with a decade of experience in the field, it's impressive to see such attention to detail.Their work somehow manages to be the right combination of cutting-edge flashiness (think Apple product landing pages) and a very down to earth usability. I can't quite put my finger on it, but it's rare to see interfaces that don't compromise one or the other at least slightly.If any of you are reading this - congratulations, you should be really proud.
