Challenge: Learn Accessibility by Building a Quiz - Step 30

Link to the challenge:

I’ve edited your code 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 (').

This value is not a valid html id value.
Please change it to start with a alphabetic character and do not use / in it
(Same for the other ids too)
