It’s one of those things that’s just not allowed. The only thing you can do is turn those imports into mixins (import the file outside the @if
and call the mixin where appropriate).
Clarification:
_partial.scss
@mixin partial {
.test { color: red }
// other styles here
}
styles.scss
@import "partial";
@if $someval == true {
@include partial;
}
