I have seen my fair share of hamburger menus over the years (the three horizontal line variety), but I hadn’t twigged exactly how old they are and yet some people still aren’t sure what they do.
Then I found this delightfully silly (in places) article all about the pros and cons of hamburger menus and it even got me thinking about ways I could be using hamburger menus differently in my own projects.
