Overriding metrics of a fallback font

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

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

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