New HTML Step 4 won't accept my code

This is where you type in a comment in html.

I’m typing in like the instructions say and it will not accept it. Says Your comment should contain the text TODO: Add link to cat photos. But that’s what’s in there. And it’s above the P element. What am I doing wrong or is there some kind of bug?

Please post your code and a link to the challenge so we can help you fix your code.

Nevermind. I got it. How do I post code?

When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).
