Newsletter #31 - Animated Credit Cards, New Animation Libraries, & Accent Color!

September 24, 2021

Gorgeous GSAP & SVG animations, a new CSS scroll API, two new animation libraries, the accent-color property, and more!


Animated Credit Cards

Our friend Tom Miller brought some brilliant animations to some fun debit card designs.

This little GIF doesn't do them justice, and there's 4 in total, so click through to the CodePens to see the smooth animations in all their glory.

Tom's using SVG elements and animating them with GSAP. The magic here is in the stellar motion design.

Pure CSS Scroll-Timeline Demo

This demo from Bramus shows off the upcoming Scroll-Linked Animations API coming to CSS. The full screen carousel uses zero JS. All the magic comes from the @scroll-timeline and animation-timeline properties in the CSS.

Right now it only works if you're using Chrome and turn on "Experimental Web Platform features" in your 'chrome://flags' section.

New Animation Libraries

This week brought two new animation libraries to the web, each serving a slightly different purpose.

Theatre.js - JavaScript Motion Design Library Theatre.js - JavaScript Motion Design

Theatre has visual timeline editing tools that you normally see in CG apps like After Effects. The great thing is it's for the web and can animate the DOM, Three.js, WebGL, and really any JS variable.

Motion One: The Web Animations API for everyone Motion One: The Web Animations API for

Motion One is a tiny abstraction over the Web Animations API, made by the author of Framer Motion, Pose, and Popmotion. It handles keyframes, timelines, and staggers, clocking in at only 3.1kb.

People are already making some incredible stuff with Theatre. I'm hoping to learn about both libraries during future streams, so stay tuned for that!


Accent Color

Why should you care about the new accent-color CSS property? One reason is that it allows you to use the built-in form elements (checkboxes, range sliders, etc) with your own custom colors.

Normally you'd hide the checkbox and reimplement your own with a bunch of CSS. Now to get a great looking set of form elements all you need is:

:root { accent-color: rebeccapurple; }

And your form is now on brand.

Demo playground from Michelle Barker

Our friend Michelle Barker wrote all about it in a Smashing Magazine article, in the best explanation I've seen of it so far. Definitely check it out!
