What is the difference between components, templates, and patterns?
Components are design elements that define a visual style and/or micro-interaction. A component is the smallest unit of measure within a design system. They can be considered concrete, a finite list: Button, accordion, table, etc.
Templates or Page layouts
Templates, or page layouts, compose components within a single page. A layout can contain multiple variations of a component depending on the context.
Patterns incorporate one or more page layouts and components to create an interaction that can span multiple pages, a short or long time span, and potentially even multiple channels. Patterns might be unique to a site or an application and may evolve with changes in technology or after competitive analysis.
A pattern is more than the sum of its parts. Patterns are solutions. In the Design System, patterns demonstrate how design, content strategy, reusable components, and accessibility can be put together to solve common problems that all Veterans may experience on VA.gov.
