More of a general question: is there a resource out there where you get to add accessibility features to a practice webpage? I feel like I could use the practice to remember the applied accessibility features and a webpage where you go through and make changes to add as much semantic meaning as possible would be useful. If not, I’ll create something in codepen and practice adding in the features.
Thanks in advance
