Hi @joy110600 !

Welcome to the forum!

When asking for help, please avoid posting screenshots.

It is always best to write code directly into the forum and provide the challenge link so we know what lesson you are on.

Based on the screenshot the error message is telling you you don’t have an id in the footer.
The footer tag is located on line 16.

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 (’).

Thanks for the help, I appreciate it .
