Stuck on replacing article with div tag - Wrap Content in the article Element

Hi Everyone,

I am stuck on the “Applied Accessibility: Wrap Content in the article Element” lesson.

It’s a simple lesson where you are supposed to change the div tag to use an article tag instead.
But I keep getting this message: “Your code should not have any div tags.” , even though I have replaced the div tags with article tags.
Seems to be a bug, or am I missing something? Did anyone else experience this?

EDIT: Seems to be an issue with Firefox, the code gets accepted by the editor in Chrome.

This is the code without any div tags that is getting rejected:

I’ve just copy n paste your code and works fine, maybe it’s just a bug. Try to reload the page.

Hm, seems to be an issue with Firefox, just tried it on Chrome and it gets accepted there.
