Thank you for your help.
This reference is helpful.
However, I find this tutorial strangely difficult to follow. It seems like it suggests several approaches, but then quickly discounts each of them as outdated a few sentences after they are introduced (?!?) because they are inefficient or depreciated or just not right. This is very weird and confusing.
So how is a user supposed to do this TODAY?
-my own markup?
Should i do this in the WP content editor or in cornerstone/visual composer?
Is there a complete page i can look at as an example?
