descent-override

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The descent-override CSS descriptor for the @font-face at-rule defines the descent metric for the font. The descent metric is the height below the baseline that CSS uses to lay out line boxes in an inline formatting context.

Syntax

css
descent-override: normal;
descent-override: 90%;

Values

normal

The default value. When used the metric value is obtained from the font file.

<percentage>

A <percentage> value.

Examples

Overriding metrics of a fallback font

The descent-override property can help when overriding the metrics of a fallback font to better match those of a primary web font.

css
@font-face {
  font-family: web-font;
  src: url("https://example.com/font.woff");
}

@font-face {
  font-family: local-font;
  src: local(Local Font);
  descent-override: 125%;
}
