An off-canvas menu is a navigation pattern commonly used in modern web design and mobile applications. This type of menu remains hidden by default and slides in from the side when activated, typically through a button or a swipe gesture. Its ability to save screen space while providing an efficient navigation solution has made it a popular choice among UI/UX designers.
Historical Context
The concept of off-canvas menus emerged from the need to optimize web navigation for smaller screens, especially in the era of mobile-first design. The rise of responsive web design around the early 2010s saw a significant shift towards more dynamic and interactive user interfaces. Off-canvas menus were adopted to address the challenges of limited screen real estate on smartphones and tablets.
