Hamburger... yummy
Make sure to look at the HTML and CSS coding on this website. It displays the required properties to make a hamburger menu.
If you like, you may copy the code. I took the time to learn this by going to W3schools. They have a ton of guides for website stuff like this.
This is mostly for me to reference whenever I want to put a responsive menu navigation. I figured it would be something that I would have to do over and over again, so this is something I made in advance for myself to learn about.
Along with that, I also have a script that makes it so the window can be dragged. See if it works on desktop!
