    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

    Overshadowed by CSS animations for almost all use cases.

    But animated gradient outlines on text is the only use-case I care about.

    Oh TIL - Thanks!

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

    Slightly related, I recently hit on this SVG animation bug in Chrome (that someone else found):

    "Use case" is written without hyphen https://en.m.wikipedia.org/wiki/Use_case

    I have to differentiate myself from LLMs by using words wrong though

    Hyphenation of multi-word nouns is a process in English that usually happens after some time of usage as separate words. It often happens before eventually merger into a single compound word noun. Such as: "Electronic Mail" to "E Mail" to "e-mail" to "email".

    Given how often it is used as a jargon term in software development, I can absolutely see this usage of "use-case" here as a "vote" for the next step in the process. Will we eventually see "usecase" become common? It's possible. I think it might even be a good idea. I'm debating adding my own "votes" for the hyphen moving forward.

    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.

    *in browsers

    Most other SVG renderers don't support much CSS.
