Defines the standard visual style for a loading indicator.
Usage Guidelines
Use a loading indicator to show that a page is in the process of loading or an action is being completed.
Features
A loading indicator provides visual feedback to users that they have initiated a process and it holds their attention for processes that take longer than one second.
(Do not use a loading indicator for processes that take less than one second since this may confuse users.)
A single loading indicator can be used at the page level or multiple indicators can be applied to specific components on a page.
Loading indicator should always appear over the content area.
Example of the loading animation.
The loading indicator may apply to either the entire page or to just the section that is awaiting a server response.
