Describe your issue

I had to add the line below to my input css in addition to changing the config file for the plugin to work. I am using tailwind v4

@plugin '@tailwindcss/forms';

I am new to tailwind, so I am not sure if this was implied. It would probably be good to mention it for those like me who are still new to tailwind.
