Skeleton Component
A skeleton is a graphical placeholder.
A skeleton is a graphical placeholder, reserving physical space in the page for content that is not yet available for the client to render. A skeleton can be considered as an alternative to the progress spinner in many situations.
A skeleton is appropriate as a placeholder for content in cases where a service or action may be slow to resolve.
A skeleton is NOT appropriate as a placeholder for content if rendering that content or placeholder would cause unexpected page layout shift.
