Under Module 1
Topic: Marking up Page ontents. - should be Contents

Also some of the list items have periods at the end and some do not. I suggest removing all periods for list items that do not contain a complete sentence.

Topic references should now be updated (and that typo should be corrected).

Thanks for raising this. Last year we discussed it in
#98
, but punctuation at the end of lists is something we may want to discuss again as we diverged a bit from our style guide.

Hey @lakeen
This should now be fixed. Please note that I reorganized module 1 according to other comments. You can see a preview at https://5ef34a4fd612ce00078e8256--wai-curricula.netlify.app/curricula/developing-accessible-content/structure-semantics-and-navigation/

I am closing this issue, but reopening #98 to deal with overall list capitalization and terminal punctuation
