Looking for critique on my technical documentation page

I made a page that’s supposed to serve a very barebones intro to playing Machamp in Pokken Tournament DX. The worst thing about it now is that the title only appears when you click the menu on mobile, but otherwise, I hope I learned from my past projects and made something that isn’t too bad. Any feedback would be appreciated. Thanks.

Thank you! I added the test suite and it passes all tests now. It didn’t before because I had a nav element with a “nav-bar” id instead of “navbar”.

Uh, I broke the page for a little while. I forgot to change all instances of “nav-bar” to “navbar” but that’s fixed now.
