[css-align] gap inconsistent with longhands #1784
Description
The initial value 'normal' for row-gap and column-gap is not consistent with the initial value '0 0' for gap.
The longhands row-gap and column-gap apply to 'multi-column elements, flex containers, grid containers', but the gap shorthand applies to 'grid containers'.
The computed value is similarly inconsistent.
The animatable wording is consistent, but it is redundant for the shorthand: 'see individual properties' would be better. This would also be appropriate for initial value and computed value.
