SGDS Background Color Utilities Skill
Helps developers use SGDS background color utilities that adapt to light/dark themes using semantic tokens.
Prerequisites
Required: Complete setup from sgds-utilities-setup skill first.
Theme files required: Background color utilities require both utility CSS and theme files (day.css and night.css) for theme-aware colors.
Core Concept
All SGDS background utilities use the sgds:bg-{variant}-{modifier} pattern with the sgds: prefix.
Background colors are theme-aware - they automatically adapt when toggling between day/night themes (unless using fixed variants).
