font-optical-sizing

The font-optical-sizing CSS property sets whether text rendering is optimized for viewing at different sizes.

Optical sizing is enabled by default for fonts that have an optical size variation axis. The optical size variation axis is represented by opsz in font-variation-settings.

When optical sizing is used, small text sizes are often rendered with thicker strokes and larger serifs, whereas larger text is often rendered more delicately with more contrast between thicker and thinner strokes.

Values: This property is specified as one of the following keyword values:

Values: none The browser will not modify the shape of glyphs for optimal viewing. auto The browser will modify the shape of glyphs for optimal viewing.
