I've read Prepositions: “in” vs. “on” a tab/widget, but it asks about widgets and I am not sure if the answers apply to more general information.
For example:
You can access the details __ the Administration tab.
You should check your doubt __ our FAQ page.
My intuition says “on”, but English is not my first language. And I am not sure about the use of onto or into in this context.
Also, if anyone has a broader explanation or link about preposition use on the web, I would be very happy to read it.
