The use case is very simple:
Instead of creating a component for “bundles of characteristics”, it would be nice to create classes that you could use to style elements.
The most common example would be within cards.
You would create a class that includes these styles for the card :
- Border radius
- Background color
And you would use this class to style every card component.
The problem now is that you can:
- Either create a card component with a slot, which is not always ideal because you have to make sure that the content always behaves as wanted within the card
- Style with variables or styles each element of the card everytime
Classes would really make life of designers easier, and make it more dev friendly.
