You’ve added extra main tags and you removed the p tags and most of the text that was in the p element. These are not things the instructions asked you to do. I would restart the step to get the orignal HTML back.
The only thing you want to do is turn the words “cat photos” inside the p element into a link. You have already done this exact thing with the words “cat photos” below the p element. You did that by wrapping the words with the appropriate a tags. You want to do exactly the same thing to the words “cat photos” in the p element. Do not do anything else.
