I'm not sure what you mean by "a", but luckily, the button included your code and linked the challenge.

It looks like you have 3 issues:

  • the "paragraphs" collection doesn't have a "style", but you you can access individual elements by indexing
  • the instructions say to change the color (text color) of each item, not the background color
  • a literal color name must be enclosed in quotes to make it a string.

I would like to delete these questions because I got what I wanted, and I think they can't be helpful to other people because they aren't sorted properly. Because of the title and etc.

Once a question has been answered, there's no longer an option to delete it, but you can always edit the question to provide a meaningful title and text. Click the rectangle with the 3 dots to expose the "Edit Question" option.
