font-synthesis-small-caps CSS property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since March 2023.

The font-synthesis-small-caps CSS property lets you specify whether or not the browser may synthesize small-caps typeface when it is missing in a font family. Small-caps glyphs typically use the form of uppercase letters but are reduced to the size of lowercase letters.

It is often convenient to use the shorthand property font-synthesis to control all typeface synthesis values.
