Step 4 html Registration Form

I’ve been stuck in this step, I don’t know what am I doing wrong here. My code is:

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 (').

Finally I could solve it. I just added a / before >
