The object-view-box and object-overflow properties allow the content for replaced elements to paint outside its content-box, similar to ink overflow for other elements.


object-view-box and object-overflow allows the author to specify a subset within an image that should draw within the content box of the target replaced element. This enables an author to a create an image with a custom glow or shadow applied, with proper ink-overflow behavior like a CSS shadow would have.
