A level or component within a design, image, or software interface where different elements can be placed and edited independently without affecting other layers. Layers are commonly used in graphic design, mapping, and photo editing software.

Layers in digital graphics or web development separate elements for easier editing and design. Knowing about layers helps users manage complex projects, especially in design, by allowing them to break content into manageable parts. Helping others understand layers ensures they can create accessible, flexible designs.
