Hey @digilou thanks so much for another question! I am definitely going to implement the accessibility category right now! :octocat:

I do find this answer a bit short, to be honest. Maybe include what is color contrast and how it benefits visually impaired users? Most of the people who use this website have very little accessibility knowledge since it's focused on beginners mostly.

Thanks for understanding, and let me know if you need any help with it. 👍

I am going to add a11y category right now to display your questions!

@fejes713 @skatcat31 I've updated the question to ask why it's important, and extended the answer to bring more clarity to someone who is trying to learn accessibility.
