Accessibility Technical Documentation project - feedback welcome

Hi there, I’ve finished my Technical Documentation Project on Accessibility. I welcome your feedback! Particularly if it seems accessible :wink: still getting my bearings on best practices with media queries, also.

Note: I submitted the code successfully through the tests on the new editor, but due to my own accessibility needs, I still did most of the coding in codepen (for my brain, the new editor is far too crowded visually to have the instructions/html/css/preview side by side, which is the only option to view everything at once). I then added the appropriate header/body/etc tags in the new editor. I also do not believe there is a simple way I can link to the code in the new editor, unfortunately. Will probably be posting this separately as feedback for mods.

Anyway! Thanks in advance for your comments.
