    First off, I'm pretty pleased with using UIElements so far - it took a while to get started, and I'm still a long way off being as comfortable with it as with IMGUI, but I'm definitely starting to see its uses!

    I'm wondering if there's any plan to bring something like the CSS transition property to USS in the future? Right now, the only way to do animated hover states or something involves a fair bit of C# code, which a) is overkill for a minor addition to a UI, and b) breaks the nice separation of concerns UXML/USS/C# brings to an extent. Being able to just add 
    transition: background-color 0.5s;
    to a USS selector would be amazing!

    Anyway, keep up the good work!

    Definitely on our radar to bring CSS Transition and CSS Animation to UIElements, for the reason you just described.

    As someone with lots of HTML/CSS experience, I am really excited to hear that this coming.

    Curious if this is still on track for a release this year. Can you use some of that IPO money to accelerate this? :D

    Seems like maturing UXML and USS for in-game UIs should be high on Unity's priority list to me.

    Actually I just read the Unity 2021.2.0a20 release notes here https://unity3d.com/beta/2021.2a. It mentions in the
    New 2021.2.0a20 Entries since 2021.2.0a19 section that "UI Toolkit: Added transitions properties to UI Toolkit."
    Are these properties the CSS Transition properties mentioned in this thread?
