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.
See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (’).
You have to make sure the h2, the comment and p are exactly six spaces from the start of the line. I would recommend you to click Restart Step and add two spaces for the h2, comment and the p OR select the h2, comment and p and press the tab key once.
