Modality
Ensure that people receive critical information and, if necessary, act on it
Provide options that let people confirm or modify their most recent action
Help people perform a distinct, narrowly scoped task without losing track of their previous context
Give people an immersive experience or help them concentrate on a complex task
Best practices
Present content modally only when there’s a clear benefit.
Aim to keep modal tasks simple, short, and streamlined.
Take care to avoid creating a modal experience that feels like an app within your app.
Consider using a full-screen modal style for in-depth content or a complex task.
Always give people an obvious way to dismiss a modal view.
When necessary, help people avoid data loss by getting confirmation before closing a modal view.
Make it easy to identify a modal view’s task.
Let people dismiss a modal view before presenting another one.
