@FatumaA, thanks for the PR! This will be a great first step in sorting out some accessibility issues mentioned in the associated issue.

For the new rules, there's no need to explicitly set all the rules to warn. Only, set the rules to warn that currently cause the build to fail.

I believe most of the issues are <div>s with 'onClicks in JSX, i.e. jsx-a11y/no-noninteractive-element-to-interactive-rolewhich also causes this rule to fail,jsx-a11y/click-events-have-key-events`.

From there, as discussed we can tackle those issues one by one, and once they're all sorted, we can remove all the rules that were set to warn so they can error by default, i.e. #4110

[FatumaA]

I've removed the rules that did not cause errors when running npx eslint . in the project root. I left about 10 rules that were causing errors.

Thanks for this @FatumaA! Looking forward to making the app more accessible!

Looks like the build is failing because of lint errors still.

[nickytonline]

Looks like some more rules need warnings still to get the build to pass.

[FatumaA]

I should have run the build locally 🤦🏾‍♀️
