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

The source for this interactive example is stored in a GitHub repository. If you'd like to contribute to the interactive examples project, please clone https://github.com/mdn/interactive-examples and send us a pull request.

text-emphasis property is quite different from text-decoration 。 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 .
