@trevor Ah, haven't worked with dynamic contents in CSS yet. What I didn't know was that the content CSS-attribute accepts sth like attr(myattribute).
pretty neat for some use-cases like the tooltips 🙂

Maybe my english isn't good enough but I don't understand your original question then.
Do you want to know how we do tooltips on our web-projects?
Do you need ideas to style the :before pseudo-element in a neat way?
What do you mean with system and title? Do you mean the title-attribute and their native browser-supported tooltips?
