Steps to reproduce

Keyframe animations declared within an element cannot be applied to the container in which they are declared (ie11 + edge). The really strange thing is that this behaviour does work in ie10.

<!doctype html>
<html lang="en">
    <meta charset="UTF-8">
    <div style="animation: my-animation 1s infinite">
        Should animate!

            @keyframes my-animation {
                to {
                    font-size: 10px;
                from {
                    font-size: 15px;

    • Sorry, the example I posted was not accurate enough. The one below actually breaks. The problem is that if the animation name is set on an element before the animation exists then it never gets applied. You can fix it by opening the developer tools and toggling the animation name

          Should animate!
    • Posting the example again - not sure why the formatting on the last one got messed up

          Should animate!
    • Well that is lame - the preview renders correctly but the server rendered one is not :(

    • To get around that problem I have attached the raw html to this issue.

    • I do not see any attachments to this exact issue, but I do see some HTML and CSS code that does not seem to repro the problem reported (seeing the same thing in Chrome 52 and Edge 10586.

      Can you try to re-attach / upload the item again please?

    • Sadly I could not upload the file:
