Hello I am trying to get the hamburger menu in front of the background but cannot get it. I have tried setting the z-index to -1 for the background and other stuff but it does not work. When I view my website on my phone the menu does not appear. IDK how to fix it. When viewed on a computer it shows up but not mobile.
Heres the code.

I’ve edited your post for readability. When you enter a code block into the forum, remember to precede it with a line of three backticks and follow it with a line of three backticks to make easier to read. See this post to find the backtick on your keyboard. The “preformatted text” tool in the editor (</>) will also add backticks around text.

I would also recommend adding a link to your codepen of the page, as this is easier to debug than looking at a wall of code.
