@bramus@front-end.social I'd argue the the use of `--arg` makes the application of the value local, which aligns more to this: https://codepen.io/Westbrook/pen/raMJByv than to what you've shared. Maybe that's not _how_ mixins work, but it's definitely how I'd read them. Your example feels more like the mixin is: ```css :root { --foo: 10em; } @mixin --foo() { @Result@mastodon.social { &, & > h2, & + p { width: var(--foo); } } } ```
