text-emphasis styling

- CR

Method of using small symbols next to each glyph to emphasize a run of text, commonly used in East Asian languages. The text-emphasis shorthand, and its text-emphasis-style and text-emphasis-color longhands, can be used to apply marks to the text. The text-emphasis-position property, which inherits separately, allows setting the emphasis marks' position with respect to the text.
