Implementing Light and Dark Mode with Style Dictionary

This tutorial demonstrates three methods for implementing light and dark modes using Style Dictionary and design tokens. It covers creating separate token files for each mode (generating either two CSS files or one combined file), and using a single token file with mode-specific values. The guide includes practical code examples showing how to structure base and semantic tokens, configure Style Dictionary build processes, register custom formats, and generate CSS with prefers-color-scheme media queries for automatic theme switching.
