#Tailwind CSS Autocomplete

Tailwind CSS provides an official extension called Tailwind CSS IntelliSense for autocompletion of Tailwind CSS class names, CSS functions, and directives in VS Code.

You can follow the steps below to enable the autocomplete feature:

1. Install the Tailwind CSS IntelliSense extension in VS Code.
2. If the root directory of your project does not have a tailwind.config.{ts,js} file, you need to create one and write the Tailwind CSS configuration for your current project. Otherwise, the IDE plugin will not work correctly.

If you use Tailwind CSS on IE 11 browser, some styles may not be available, please use it with caution.
