Design Philosophy

The styles contained in Mortar reflect National Geographic's overarching design philosophy. We pride ourselves on stunning, world-class visual storytelling. By keeping design elements minimal, we are able to allow our content to drive the visual presentation of our digital products. The design should never feel heavy or overpowering.

Refer to the pages in this site to create a repeatable, visual language for users interacting with the National Geographic brand on any digital platform. Our color palette, typographic styles, icon library, and page grid help to create consistent patterns, clean lines, and beautiful displays for our content.

By standardizing and documenting our design patterns in Mortar, we are striving to create one consistent user experience and brand identity for National Geographic across all of its digital products.
