Maps never only channel
maps-never-only-channel
Maps are never the only channel — text-based alternative always. Aspect ratio must differ from the viewport so mobile users can still scroll the page; leave space around the map and a close/minimise control.
Description
Maps are never the only channel—a text-based alternative always exists. Aspect ratio must differ from the viewport so mobile users can still scroll; leave space around the map and a close or minimise control. Pass when a text alternative exists, aspect ratio is not the full viewport, and close/minimise plus space around the map exist. Fail when the map is the only channel or fills the viewport so the page cannot scroll.
When to use
Embedding maps as a primary or supporting information channel.
Not when
Map-only content or maps that fill the viewport so the page cannot scroll.
Agent hint
Always provide a text alternative; leave space and close or minimise so the page scrolls.
A text alternative exists; map aspect ratio is not the full viewport; close/minimise and space around the map exist.
Map is the only channel; map fills the viewport so the page cannot scroll.
