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.
Mind that space between the href attribute and the self-closing tag. Never seen it before in the lessons or maybe don’t remember but that’s how it shows as correct.
