+<p>A propriedade CSS <strong><code>font-kerning</code></strong> controla o o uso da informação de kerning, que é, o controle de como as letras serão espaçadas. A informação de kerning é armazenada na fonte, e se a fonte é <em>well-kerned</em>, essa caracteristica permite que o espaçamento entre caracteres seja muito parecido, independente dos caracteres.</p>
