CSS Font Smoothing in Webkit and Firefox

Michael Gearon · March 11, 2016

Using font smoothing can turn a horrible typeface to a beautiful one. The Webkit and Firefox browsers make the fonts look slightly thicker, using just two lines of CSS we can solve this problem.

Syntax

The default value for -moz-osx-font-smoothing is auto. This will work in Firefox using the -moz- prefix, and for it work in Opera, Safari and Chrome use the -webkit- prefix. This is not supported in any version of Internet Explorer or Edge.

body{
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale; /* Default: auto */
}

Example

Static Example

The top version is antialiased, whilst the bottom is not.
