font-synthesis-position
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
The font-synthesis-position
CSS property lets you specify whether or not a browser may synthesize the subscript and superscript "position" typefaces when they are missing in a font family, while using font-variant-position
to set the positions.
The font-synthesis-position
property has no effect when using the <sup>
and <sub>
elements.
It is often convenient to use the shorthand property font-synthesis
to control all typeface synthesis values.
