Formatting a Page with Comments or Questions in a Separate Box

Hello!

I would like clarification on is whether I am able to create a separate box of text on a page apart from the main body of text. What would this look like? I would like the main body of the text on the page but then, on the side, be able to have a separate box of text where I can list questions or maybe some other bits of information to consider.

Is this possible? If so, could someone point me in the direction of learning how to format this?

Thank you for your help!
