So animated GIFs can be replaced by Animated PNGs with alpha blending with transparent backgrounds and lossless compression! Some nostalgia from 2000s websites can be revived and relived :)

Curious if Animated SVGs are also a thing. I remember seeing some Javascript based SVG animations (it was a animated chatbot avatar) - but not sure if there is any standard framework.

Yes. Relevant animation elements:

• <set>

• <animate>

• <animateTransform>

• <animateMotion>

See https://www.w3schools.com/graphics/svg_animation.asp

Oh TIL - Thanks!

This could possibly be used to build full fledged games like pong and breakout :)

SVG also supports Javascript, which will probably be a lot more useful for games.

It supports JavaScript when used as a document, but when used as an "image" by a browser (IMG tag, CSS features) JavaScript and the loading of external resources are disabled.
