Yes, everything can be overridden with Tailwind classes (i.e. `btn p-8`). It's a great choice you're a Tailwind enjoyer, but want the batteries-included experience of Bootstrap.
Somebody who likes Tailwind would have an easy time specializing DaisyUI to look exactly like what they want. For that matter you could make Tailwind with DaisyUI easily. Their examples look great and I could totally see using DaisyUI instead of Bootstrap on my side projects, though my current ones have real back end problems that need solving and reworking the CSS isn't on the agenda any time soon.
