centralize (some) CSS colors to the .theme-{light,dark} definitions
Created by: sqs
We have 2 color themes: light and dark. To support additional themes, we need a central place for each theme's colors to be defined. This PR is a step in that direction.
Right now, most theme colors are defined in colors.scss
. But not all. For example, form colors were defined in forms.scss
. With this PR, they are now defined in colors.scss
for each color theme.
This PR does not centralize all color definitions, but it does reach many of them.
There is no (intended) user-facing change from this PR (i.e., no UI colors will actually change; this is just a code refactor). (I will confirm that on Percy.)
