cdoublev has just created a new issue for https://github.com/w3c/csswg-drafts:
== [css-animation-1] Limit keyframe rule to `@keyframes` context ==
This seems to be a minor problem but... I cannot find some definitions that prevents this:
```css
@media all {
from { translate: 0px; } /* keyframe rule */
}
```
In CSS Syntax 3, [`<stylesheet>`](https://drafts.csswg.org/css-syntax-3/#typedef-stylesheet) (the block value type of `@media`) is defined as:
> the `<stylesheet>` production represents a list of rules. It is identical to `<rule-list>`, except that blocks using it default to accepting all **rules that aren’t otherwise limited to a particular context**.
> For rules that use `<stylesheet>`, all rules are allowed by default, but **the spec for the rule may define what types of rules are invalid inside the rule**.
CSS Animation 1 does not limit `<keyframe-block>` (keyframe rule) to `@keyframes` and CSS Conditional 3 does not prevents `@media` from containing `<keyframe-block>`.
If I'm not mistaken, the issue is also valid for `@supports` and/or margin rules.
