Hi @marvin-j97 ! Thank you for putting this PR in.

Before I get to reviewing this, do you mind fixing it so the deploy preview works? The error I'm currently seeing on our Netlify logs is this:

git ref pull/1185/head does not exist or you do not have permission

Not sure what that means - that is a Netlify error... forks are always public anyway.

We need the deploy preview to work to make sure the build doesn't break. Could you either fix this PR, please, or re-submit the changes in a new PR one so it works?

There's nothing I did though that should prevent pulling the PR on Netlify's side... I just changed a markdown page.

Edit: I just noticed it built fine.

The page could probably use a warning banner if we 100% know classList will be removed in v2.

@marvin-j97 thanks for the contribution.

We will leave any depreciation warnings until things are confirmed.
