Spacing tokens give you the ability to define values for Auto Layout that you can reuse. Once you applied a spacing token to a layer, it will get updated whenever you change that token, so any layer containing a reference to
$spacing.container will get updated, when you update that specific token.
In order to make spacing tokens work, start by creating tokens in the Spacing category.
Then, select or create an
Auto Layout layer (it will not work on any other layer type!)
Once selected, apply Spacing tokens by either left-clicking (all values will use this token) or right-click to specify which part of the Auto Layout you want to target (
vertical. Others are following soon)
