Hi ​@figma_admin 
Although CSS grids are useful for consistent box sizes and much more. But inside Figma, I just noticed the width of 12col. grids with 20px gutter are varying. These were supposed to be equal.
But these are same when we change gutter to 24px, the problem arises when we use gutter 20px in 12 col-grid.
I attached ss for clarification.
Have anyone noticed this before?
