M365 UI Kit
The Microsoft 365 UI Kit helps you to design apps that span the Microsoft 365 ecosystem. It includes core components, scenario-based templates, and best practices to help you create apps that keep your users in the flow of their work. The kit also explains app capabilities, shows common use cases, and covers fundamental design concepts (such as responsive sizing and accessibility). You can easily grab design elements and modify them as needed, giving you more time to create the best experience for your users. A well-designed app for Microsoft 365 can save users time by avoiding context switching, providing users access to the functionality they need where they’re already working.
