Override the browser's default rule for kerning pairs of adjacent characters.
Font kerning is used on most serif and sans-serif fonts, following the rules established by the font designer. When enabled, each pair of two letters is carefully tweaked to be closer or further apart, using hints that the designer embedded in the font file.
Kerning is usually desirable for all but the tiniest of font sizes, when it becomes a hindrance to legibility.
Override the system's behavior regarding the use of kerning:
|normal||Font kerning is enabled|
|none||Font kerning is disabled|
|auto||Let the browser decide whether or not to use kerning, based on the size of the font|
