Tailwind CSS Language Mode Formatter VS Code Extension

Tailwind CSS Language Mode Formatter is a Visual Studio Code extension that formats .css files when their language mode is set to Tailwind CSS.

This extension was created to address the need for formatting custom CSS within Tailwind projects, as Visual Studio Code does not provide a built-in Tailwind CSS formatter.

To use the extention, open the Command Palette and type >/tailwind Format File, or press the shortcut Alt + Shift + F.

Ensure you are using the Tailwind CSS Language Mode, check the screenshot below.
