yarn init
This will take you through creating a package.json file, for our purposes I left all the values at their defaults. Once complete you should have a package.json file inside your project’s folder.
Now that Tailwind is installed, it’s time to start testing it out. To do this, we’ll create a basic website file structure. Here’s how I set that up… In the root of the project’s folder I made an index.html file and a styles folder. Inside of the styles folder, I created a styles.css file.
Once that was done, I added the following Tailwind directives into the styles.css
@tailwind base;
@tailwind components;
@tailwind utilities;
In your command prompt window from before, select your styles folder that you made
cd styles
With that selected, run the Tailwind CLI tool with the following command
npx tailwind build styles.css -o output.css
If run successfully, you should now have an additional file in your styles folder named output.css which means you have successfully installed Tailwind CSS, all there is left to do is test to make sure.
