The CSS font-kerning property defines the way specific pairs of letters are spaced.

You see, fonts often contain information about how much breathing room a character has on its left and right edges.

The proper term for the spacing is sidebearings.

When two characters are placed next to each other, their sidebearings add up to form the actual space between characters.

The right sidebearing of A and the left sidebearing of V define the space between them.

Font designers will adjust the sidebearings between two specific characters so they look better together. That’s kerning and that’s what the font-kerning property lets us decide: whether we want to use the font’s kerning or disable it altogether. So, if the font you’re working with doesn’t support kerning data, then this property will have no effect on it.
