Hello colleagues,

I really appreciate you making effort to improve Tailwindcss framework (●'◡'●)

And my topic here is a Dark Theme for Docs.

I would be grateful if you realize it like in Docs of v3. Or may be better than in v3 (❁´◡`❁)

Excuse me, colleagues. I found a theme switcher in the bottom of the Docs page ╰(°▽°)╯
