Q: What's "hamburger button" means? I read a sentence

Instead of a menu bar and a toolbar, we will use a drawer from which the user can pick the actions. The drawer can swiped in from the side, but we also offer a hamburger button in the header.

What does a 'hamburger button' mean?

A: In English, 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.
The button shows three horizontal lines or bars stacked vertically suggesting items in a list, and is named as it is because it slightly resembles the three elements of a traditional hamburger in a bun.
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.
