I want to add `!important` to a mixin. I tried both the following ways, and they return an error:

```
@include linear-gradient(hsl(68%, 94%, 90%), hsl(68%, 90%, 80%)); !important

@include linear-gradient(hsl(68%, 94%, 90%), hsl(68%, 90%, 80%)) !important;

```

Is there a way to do this correctly?
