I’ve edited your post for readability. 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.
I see two issues. First, you have an extra closing curly brace (}) after your .pink-text class - that might be confusing the CSS. Also, you have two classes in your h1. (I don’t know if that is a problem or if it is part of the challenge.)
