Sure, for I guess moodboardin’ it be for aesthetics.
Functional the use case would be for speed and consistency. Creating form like spaces and quickly accessing how much gaps I need but numeric value that would be consistent, so I can replicate again in another area; some what also aesthetic as well.
Currently it’s a cut and measure game till it looks right or close enough.
Specifying gaps would also work as reference for future space/area creation as there is a numeric value to reference. (Though you could use templates, I guess its an alternative if you rather not inherit the template styling.)
so in this case you want to create a form like space but you want the elements to be some other distance than 12 px between them, mainly for aesthetic reasons right?
