The button hiding the menu: clicking or tapping it, user sees the menu expanding. It is called so as its form consisting of three horizontal lines looks like typical bread-meat-bread hamburger. Nowadays it is a typical element of interaction, still highly debatable due to the number of pros and cons.

Most users who visit and use websites on the regular basis know that this button hides the core categories of data so this trick does not need additional explanations and prompts. Hamburger menus free the space making the interface more minimalist and full of air as well as allow massive saving place for other important layout elements. This design technique also provides additional benefits for responsive and adaptive design hiding navigation elements and making the interface look harmonic on different devices. Although hamburger menus still belong to highly debatable issues of modern web and app design, they are widely used. The arguments against hamburger menu are based on the fact that this design element can be confusing for people who do not use websites regularly and can get misled with the sign which features a high level of abstraction. So, the decision about applying hamburger button should be made after user research and definition of target audience’s abilities and needs.
