The pixel pipeline in the browser is often causing animations to be a lot slower than they can be. Different CSS properties cause in validations on different layers. You can use transform and opacity to avoid layout and skip some of the steps.pic.twitter.com/SMFolFwDQ9

Now @JoshWComeau shows an accordion he built where he avoids layout calculations to render fluidly on all devices. The second example is a like button with a particle effect like the one on https://twitter.com . Now he’s using http://jspaint.app to explain the math. pic.twitter.com/ogOdPKd6Nz

A painting showing how to use some to calculate some of the trigonometry.

Sprites can help make the animation even smoother. Sprites are pre-rendered images of every frame which avoid all the work since the image is already rendered!pic.twitter.com/FKJCun4oZ7

In React Spring, you don’t need timing functions. Everything is based on spring physics. You can tweak the parameters to get different feels. Check out some of the presets (more in the recording):pic.twitter.com/uUOkOyUWJH

Now on stage: @ellatrx on designing the rich content editor for @WordPress. The previous editor was entirely relying on contentEditable and used the DOM as the source of truth. One giant problem with this is that you always end up getting an element soup.pic.twitter.com/3p80m6mN3d

The new editor, Gutenberg, works differently. Everything (E.g. headlines, subtitles) are described as blocks. Blocks use HTML with special comments to describe the behavior. All of the HTML is parsed into an object tree.pic.twitter.com/PIc66OgwGp

For backward compatibility, pages created using the old editor will be migrated into one special legacy block for the new system. Beautiful!

For rich text content block, Gutenberg ended up writing up their own <RichText> components in React using contentEditable under the hood but making it a controlled component. Key strokes and input events as well as the DOM content are used to map to the next state.pic.twitter.com/qnKF3mruEl
