Hello, I have linked to a repo I was using before I migrated from Bootstrap to Flowbite. The repo has core_components.ex with Bootstrap styles. I have striped away the personal stuff so it’s just a bare dashboard template. I have added some simple LiveViews for Product and ProductCategory to see the components in action.
Repo: GitHub - jmnda-dev/phx-bootstrap-dashboard: A Phoenix framework bootstrap dashboard with Bootstrap styles `core_components` · GitHub

The Modal and some form inputs have some of their styles in the app.scss file. You can follow the ReadMe for setup instructions.
If you have any questions let me know.

It shouldn’t be too difficult, just a bit time consuming.

You could start by converting all the tailwind classes to inline styles. With the exception of a few css variables that’s rather straightforward translation. Then you’d have equivalent functionality but no longer need tailwind dependency.

After that you can migrate to bootstrap at your leisure. See Phoenix 1.8 and Bootstrap 5 · FullstackPhoenix for some ideas on this.

Thank you so much. It really helped me.
