Tailwind forms plugin

Hi im following the Laravel from scratch series, and im trying to create a "create blogpost form". I read online that I needed the Tailwind/forms plugin to style my input fields and selectors. I added it by running

"npm install @tailwindcss/forms" and then referencing it in the tailwind.config.js file like so:

"plugins: [ require('@tailwindcss/forms'), ],"

Then I added the https://tailwindcss-forms.vercel.app source code to my post.create view to test the plugin, but my site still looks completely unstyled, an nothing like the example? am I missing a step?

I tried running both "npm run watch" and "php artisan serve"

Best regards Emil
