Should I use tailwindcss 4 or 3? Some component use 4 features.

[XMethues]

css variables are wrapped by brackets in 3 and parentheses in 4.
For example, sidebar components currently are using w-(--sidebar-width), but the cli generates templates are only for 3.

Hello, you should definitively use Tailwind V4, i use it on my own project.
You should also use the css file shared on this issue.
You can also follow the addition on TW4 on Solid-UI through this issue :)
