TailwindCSS and React18 Support

[NiluK]

Hey folks awesome project.

Really, liked the notion style UI and the way it's all coming together.

Is there a way to make this work on React 18? Right now it's erroring a bit since it depends on ReactDom.render();

Also TailwindCSS support would be very much appreciated. Though, do love mantine.
