Hey! Thank you for updating the examples. But I noticed that there’s more than just CSS here.

We discussed it in the content team and agreed that changing example content doesn’t add much value (it wasn’t broken), but the opposite: it changes relatively neutral text into heavy and somewhat disturbing one. This change is also missing from the PR description, although it takes up to half of the changed lines.

I would suggest reverting the old demo text and focusing on the code as the most valuable part of this example.

I changed it to Dr. Seuss, so the user can better see which line they are on as it scrolls

Looks good! Thank you 🙂
