comp space - Respo/respo.calcit GitHub Wiki

This is the component to add spaces. It decouples whitespaces from margins of elements, so I consider it a good practice.

; "for horizontal space"
comp-space 8 nil

; "for vertical space"
comp-space nil 8

Make sure that one of them left nil so the component may fill it.

It's also okay to use strings:

; for vertical space
comp-space nil "|8px"

The bad aspect is every <div> actually costs. And margin is still an alternative solution.

Notice, marge is more performant than an extra element. Make you choice when you feel your app is slower.
