Syntax

Values

auto: This keyword defers to the browser regarding whether to use kerning. When the font size is small, font kerning may look strange and browsers will disable it. This is the default value.
normal: This keyword requires kerning to be applied.
none: This keyword prevents the browser from using the kerning information stored in the font.

Formal syntax

font-kerning = 
  auto    |
  normal  |
  none

p {
  font-kerning: none;
}
