Hey @kris thanks again for reaching out!
Indeed because Storybook does not run into the Next.js context adding TailwindCSS to Next.js doesn't make Storybook aware of it, you have to install TailwindCSS on Storybook's end too.
I'm not super familiar with the React ecosystem so I found some links that might help you set up TailwindCSS on Storybook:
- a rather recent blog post about TailwindCSS + Next.js and Storybook
- another blog post about TailwindCSS + Next.js and Storybook
- a TailwindCSS + Storybook boilerplate
Let me know if that helps! Happy to dig more into it~
