need product differentiation?

overhire a #CSS front-end team and ask them to:
- polish whatever
- add delight wherever

and watch as your product becomes smooth and buttery while everyone else's gather dust and crust

UI is a huge space offering differentiation via quality

We implemented a new value for `background-clip` called `border-area`. It lets you use CSS fill a border with a background image or gradient.

This article explains how it works, and shows up the possibilities in 7 demos.

Know the animated 🌈 border + glow effect that's all the rage? It's normally done by adding an opaque cover on top of two 🌈 layers.

But what if we wanted a (semi)transparent background within the border? It's possible with pure #CSS!

#CSS trick not enough folks know about:

painting into the sub boxes of an element
- border
- padding
- content

you can paint into one, or all of them differently!

here's a gradient border, a solid padding fill, and a gradient content (inner) box

I made a thing: scroll-driven, almost pure #CSS infinite circular gallery rotation - check it out on @codepen.io:

Using scroll-driven animations and the tiniest bit of JS for the infinity part of it.

Made with 🖤 for this week's #CodePenChallenge.
