text-emphasis

Summary

The text-emphasis CSS property is a shorthand property for setting text-emphasis-style and text-emphasis-color in one declaration. This property will apply the specified emphasis mark to each character of the element's text, except separator characters, like spaces,  and control characters.

The text-emphasis property is quite different from text-decoration. The text-decoration property does not inherit, and the decoration specified is applied across the whole element. However, text-emphasis does inherit, which means it is possible to change emphasis marks for descendents.

The size of the emphasis symbol, like ruby symbols, is about 50% of the size of the font, and text-emphasis may affect line height when the current leading is not enough for the marks.

Syntax

/* Initial value */
text-emphasis: none; /* No emphasis marks */

/* <string> value */
text-emphasis: 'x';
text-emphasis: '点';
text-emphasis: '\25B2';
text-emphasis: '*' #555;
text-emphasis: 'foo'; /* Should NOT use. It may be computed to or rendered as 'f' only */

/* Keywords value */
text-emphasis: filled;
text-emphasis: open;
text-emphasis: filled sesame;
text-emphasis: open sesame;

/* Keywords value combined with a color */
text-emphasis: filled sesame #555;

/* Global values */
text-emphasis: inherit;
text-emphasis: initial;
text-emphasis: unset;
