Fix "Tailwind CSS IntelliSense Plugin Not Working in Tailwind v4"

The IntelliSense plugin in VS Code may not work as expected with Tailwind CSS v4, but a simple fix can resolve the issue. In previous versions of Tailwind, the IntelliSense plugin automatically detected the configuration, but with v4, it needs to be told where to look. The plugin now needs to be directed to the main CSS file where Tailwind is imported using @import "tailwindcss". To fix the issue, users need to update their VS Code settings by adding the path to their main CSS file. This can be done by adding a line to the .vscode/settings.json file, such as "tailwindCSS.experimental.configFile": "src/styles/main.css". This tweak ensures that the IntelliSense plugin knows where to find the Tailwind configuration, restoring class suggestions. A sample project structure is provided to illustrate where the main CSS file and other project files should be located. By updating the VS Code settings, users can eliminate IntelliSense issues and keep their development process running smoothly. The official documentation for this issue can be found on the Tailwind CSS IntelliSense GitHub page. Updating the VS Code settings is a straightforward change that ensures users always have the correct Tailwind class suggestions at their fingertips.
