Test bar not appearing on my pen(technical documento project)

I am not being able to test my test my Technical document page because although I am using the script
tag with the link https://gitcdn.link/repo/freeCodeCamp/testable-projects-fcc/master/build/bundle.js, the test bar is not appearing on the screen.

Here is the link for my pen:

something about your html is causing the burger icon to not appear. (as a quick test, I removed all the html except for the script and it shows up).

I suggest you go through your html carefully to see what might be the cause.

Edit: some of the mistakes I found include,

  • opening tags without matching closing tags
  • misspelled tag names

that fixed my problem, THANK YOU very much.
