text-emphasis

The text-emphasis CSS property applies emphasis marks to text (except spaces and control characters). It is a shorthand for text-emphasis-style and text-emphasis-color.

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.

text-emphasis doesn't reset the value of text-emphasis-position. This is because if the style and the color of emphasis marks may vary in a text, it is extremely unlikely that their position will. In the very rare cases when this is needed, the property text-emphasis-position.

Constituent properties

This property is a shorthand for the following CSS properties:

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;
