Three short lines stacked one above the other, and everyone knows to tap them. The hamburger menu is one of the most recognized symbols in interface design, the standard opener of navigation drawers, the little handle that swings a hidden panel of links out from the edge of a screen. Its name comes from the obvious resemblance, two buns and a patty rendered as three horizontal bars, and that friendly shorthand has followed it everywhere. Its familiarity was earned rather than given. Decades of mobile use taught people what those three lines mean, until the icon became effectively self-explanatory, understood without a label across nearly every app and site.

That is a genuine achievement, and it is also the source of the icon's one real weakness. For all its clarity, the hamburger still hides everything behind a tap. Whatever navigation lives inside is invisible until someone decides to open the drawer, and destinations tucked out of sight get visited less than destinations kept in view. This is why the honest advice is to reach for it only when you have to.

When a screen has four or fewer places to go, visible tabs almost always serve users better, keeping every option on display where it can be seen and reached without a hidden step. The hamburger earns its keep when the list of destinations grows long enough that showing them all would clutter the screen more than concealing them costs. Different icon libraries draw and name the same three lines in their own way. Heroicons files it under bars-3, a plain description of the shape, while Tabler calls its version menu-2, naming the job instead. The glyph stays the same across all of them: three lines, one tap, and a drawer of everything you chose not to show up front.
