How do I trigger some jquery action based on screen width of the browsing window?TRIGGERING JQUERY BASED ON MEDIA QUERY?

I want to hide the menu(vertical) when the browser width is 520px or less. And replace it with a button called menu and toggle the menu by clicking on it.

You can either trigger in javascript with the proper event or trigger in css with a media query, which I believe is how Chalkley does it in this series of Treehouse videos on how to create a mobile menu to replace a desktop-style one.

You'd probably be interested in checking out the matchMedia window function.

if (window.matchMedia("(max-width: 520px)").matches) {
  // Code that runs at 520px and below to enable the mobile menu
} else {
  // Code that runs at 521px and above to disable the mobile menu

In addition, you can combine this with resize events to make sure the person browsing always sees what you intended, even if they resized it after load.
