Utilizar caracteres especiales en CSS con pseudo elementos after: y before:

Utilizar caracteres especiales en CSS con pseudo elementos after: y before:

Ejemplo: El simbolo © en html es ©. El numero ASCII es 169.

Puedes entonces convertir este número. Por ejemplo con el convertor ENTITY CONVERSION CALCULATOR, puedes hacer la conversión.

Por ejemplo con ®. El codígo html es ®

 

 

 

Podemos entonces crear una class para todas las palabras que requieren el simbolo register.

.reg:after {content:"\00ae";}
