I used your script from Downloads ("3 - Set Inline Style") . I saved changes in my Workspace and loaded the page. There is an error in the Console :( I don't know what's wrong. Can you please help me?

Treehouse StaffHey Katarzyna Wójtowicz 👋
Looks like there's something wrong in the workspace for this specific video in that it that doesn't completely match with the video. In the workspace the .btn-main
element doesn't exist in the DOM. To fix this you'll want to update the button element on line 16 of the index.html
file to have a class of btn-main
instead of an id 🙂
Sorry for the confusion there, I'll make sure that the workspace will be updated accordingly!
