What is the hamburger icon used for?

The hamburger menu, or the hamburger icon, is the button in websites and apps that typically opens up into a side menu or navigation drawer. It was created by interaction designer Norm Cox for the Xerox Star personal workstation in 1981 as an easy way to communicate to users that the button contained a list of items.

Which is the hamburger icon?

Is hamburger icon good?

Hamburger menus might be a great solution for mobile devices with limited screen space, however, translating the same mobile-first design into your desktop without any changes may cause a bad user experience. Putting your most important pages in hidden navigation could sabotage them.

Why not to use hamburger menu?

One of the biggest downsides of a hamburger menu is that it hides information. Some users don't get the chance to see how much value the app will provide before those 10 to 20 seconds are up. If the hamburger menu icon is difficult to spot, visitors will have a hard time navigating the site. And many will leave.
