Documentation: How do the `[ class ]` styles work?

[jonnyburch]

I'm not familiar with the square-bracketed classes. It looks to be something to do with config-set styles but it would be great to have explicit documentation (or a link to some) that explains how it works in this context.

This is purely a grouping mechanism for classes. It helps me scan things easier.

I’ll certainly add some documentation about it though.

@jonnyburch @hankchizljaw I started using hylia yesterday (thanks for the great starter!) and also noticed the grouping of the classes. This article on CSS Tricks came in very handy for me. Maybe worth mentioning in the documentation?
