Spinners are used as indeterminate progress indicators to show the user that there are processes happening in the background.
- Indicating to the user that loading is occurring in the background.
- Loading times are indeterminate.
Don’t use when
- A loading scenario needs to indicate progress, usually with particularly long load times. Use a dynamically updating Progress Bar instead.
- A main loading state is needed, such as an app initialization. In this case, forego our simple spinner, and opt to use a custom, branded one instead.
