text-emphasis styling

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.

Notes

Some old WebKit browsers (like Chrome 24) support -webkit-text-emphasis, but does not support CJK languages and is therefore considered unsupported.

  1. Partial support refers to incorrect support for -webkit-text-emphasis-position. These browsers support over and under as values, but not the added left and right values required by the spec.

  2. Can be enabled in Firefox using the layout.css.text-emphasis.enabled flag

* Partial support with prefix.

Bugs

  • Chrome on Android occasionally has issues rendering emphasis glyphs correctly.
