Nimble vs Tailwind CSS

I do prefer to write things from scratch however when it came to wanting to jump-start the frontend, I found that it was taking me a lot longer hence why needing to use something very fast.

Bootstrap was the boom when it came out, I didn't like it, to be honest, set in its way and a pain to over-ride and in addition, you can tell from a distance if you're using boostrap and as everything looks the same.

I came across Tailwind CSS as I wanted more dynamic features, you could say, I've been now doing it for a few days and I love it a lot. I've been practising with the full stack part installed but I an't we wait until I do a new project, and I'll e able to select exactly what I want. Much faster.

I am planning to redesign my entire application, which is currently in Bootstrap. I heard about Tailwind CSS, and I think its really cool to work with. Is it okay if I use Bootstrap and Tailwind together? I can't remove Bootstrap altogether, as my application is using the js dependencies of Bootstrap, which I don't want to disturb.

We are re-modifying the existing portal to the new one. Looking out for a CSS framework where over-rides are possible, the performance of page loading, extendable, etc Please suggest between tailwind, UIkit and bootstrap frameworks explaining in detail on different factors. I request your help on the same.
