Syntax Highlighting for Tailwind CSS

VSCode extension that adds syntax highlighting for tailwindcss classes in HTML, JSX and TSX files.

This project is financed by the community. If you or your company benefit from this project, please consider becoming a sponsor or making a one-time donation. Your contribution will help me to maintain and develop the project.

Customization

The colors of the syntax highlighting should in most cases be customized in the user settings of vscode. To open the user settings you can open the command palette with F1 and search for Preferences: Open User Settings (JSON).

You can use the Developer: Inspect Editor Tokens and Scopes command from the command palette in vscode to find out the scope of a specific token.
For custom styling you should always use the *.custom.tailwindcss scope.

Want to further improve the readability of your tailwindcss classes?

Check out eslint-plugin-readable-tailwind to automatically break up long tailwind class strings into multiple lines based on a specified print width or class count.
