The split element issue
Specify how to render an element's border, margin, padding, and shadow when it is split at a page break, or when an inline element spans more than one line.
Use one of these keywords:
|slice||The page-split parts of the element are drawn with partial boders and shadows as if the original was rendered as a whole and then cleanly cut into pieces|
|clone||The page-split parts of the element are each drawn with fully complete borders and shadows as if they were two separate elements|
