About font-size-adjust

The font-size-adjust CSS3 property allows you to specify the aspect ratio between upper and lowercase letters.

Browsers that support this property will adjust the x-height of a fallback font. By using this property you can ensure that font metrics are more consistent throughout a font-stack.
