Small overlays containing help content for complex interactions.
When to use this pattern
Only use contextual help to explain things like business processes. It shouldn't be relied upon to solve design problems - services should always be simple and intuitive. See the GOV.UK Service Standard. Contextual help is more suited to complex internal services.
How it works
Help should be easy to close, move and minimise until the user needs it.
If contextual help doesn’t answer a user’s question, links to more comprehensive help should be easy to find. GDS has guidance for help content .
