The main page of my web site has a toolbar with a hamburger menu. When clicked, a sidebar slides open from the left. That menu contains the main sections of the web site. Within each section is a second toolbar with another hamburger menu for navigating the section.
All of that is working except that the main slidebar fails to push the page sidebar over, it just overlays it. Also, the page toolbar fails to change to the background color I define.
I've created a sandbox to demonstrate. Clicking on the main hamburger menu should slide the page hamburger menu over, instead of overlaying it.
I've been trying to use the css transition margin-left, but it doesn't obey.
