I broke my old laptop, and decided to full send Linux Mint on the new one without ever using Linux before. I'm trying to help some people study math. I want to put together like 10 questions, and below them have the answers as well as the shown work to get to the answer. I'd like to be able to blur/black the answer section out until clicked or something.

I can always put the answers on a separate page or something, but thought I might as well see if Linux has something to offer

I could also code something into a webpage, but I was just looking for convenience

Thank you!
