Blazor Spinner - Simple, Animated Circular Progress Indicator

Overview

The Blazor Spinner component denotes when long-running tasks are ongoing, tasks for which there is no information about their progress. The component provides circular progress indicators without interaction capabilities.

To show users the progress information of a task, the Blazor ProgressBar component should be used, instead.

Spinner intergration

The Spinner component can be rendered with other Blazor components, such as the Tab component. To render the Spinner inside the Tab component, the Spinner is set as a child of the Tab component, and the Spinner can be shown or hidden when switching between tabs.
