Am I the only one who finds the title abrasive? Why “rules”? Who are you and why should I listen to you? Will you send the tutorial police around if I ignore you? Maybe “recommendations” would be a better choice?

I am very, very surprised about the competence of the commenters here. I have had many discussions on reddit about the advantages of meaningful instead of presentational class-naming and you’re normally met with great resistance, especially with users of frameworks like Bootstrap and Tailwind.

Here, everyone seems to either ‘get it’ or is willing to hear why classes like .lime are bad. Very cool.

I know! What a mistake of a framework. Glad my colleagues drummed it out of me.

Exactly this. Bootstrap killed the css star.
