Looking at your code, I think you get the idea of links and paragraphs. I suggest you reset your code (this is the simplest way) and then work though the instructions again noting spelling and spaces. The only instruction you need to follow is:
Now nest your existing a element within a new p element (just after the existing main element). The new paragraph should have text that says “View more cat photos”, where “cat photos” is a link, and the rest of the text is plain text.
You need to ignore the example they have given, which is (I think), where your problem has come from. If you get stuck, feel free to paste you updated code and I’ll tell you if you’ve gone wrong.
