Setting up Tailwind CSS v4 in an Angular 20 workspace involves installing dependencies, configuring PostCSS, integrating core styles into your global stylesheet, and running a build to verify the styling works correctly.

Fixing a broken PostCSS configuration for Tailwind requires merging or re-establishing the PostCSS setup deterministically so Angular processes Tailwind directives correctly during the build.

Migrating from Tailwind CSS v3 directives to v4 in Angular requires updating your global stylesheet wiring to integrate Tailwind's new core styles and adjusting PostCSS configuration to match the v4 setup.

Yes, enabling dark mode class toggling with Tailwind CSS v4 in Angular is supported as an optional feature during the setup process, alongside the ability to exclude preflight styles.

Tailwind CSS v4 works with Angular 20 workspaces by using a deterministic PostCSS setup and stylesheet wiring to ensure the framework's utility classes function correctly within the application.

Tailwind CSS styling may not appear if the PostCSS configuration is broken or the global stylesheet wiring is incorrect. Verifying the build output and validating preflight behavior helps confirm the setup is functional.
