How to quickly build a WordPress Theme using Blocs

Hello!
I want to build a WordPress Theme using Blocs, I’m looking for best practices to get started using it, I also would like to know how to quickly style elements on the right side of the Bloc editor (Similar to Webflow) without having to have a style popup that I have to move around to style elements.

The quickest way to start is the video series on Youtube: Building a Wordpress Theme - Section 1 - Introduction - YouTube

I’m not a Webflow user, so I’m not quite getting what you mean with “style elements on the right side of the Bloc editor”. Could you elaborate?

I made a video showing what I want to accomplish: https://drive.google.com/file/d/1A3qU3C9iEBJIaZztgjJfRGVbH-hwS0eU/view?usp=sharing

Thanks for clarifying that. Having the class editing in the right hand sidebar would need a structural change to the program itself. As far as I know this isn’t currently possible.
