Grouping mechanism []

[husseinalhammad]

The examples in the documentation groups classes inside brackets [], but I don't think this was explained (unless I missed it). I've seen this grouping mechanism in CUBE CSS. Perhaps adding a brief explanation would help readers who are not familiar with this.

Sorry to spam, but given I'm only starting to dive into this it may be easier for me to point out these things now while they're fresh.

This is great feedback, really appreciate the suggestions!

Completely agree, just wondering where to include this without including it everywhere they're used
