+ 5 Font Matching Algorithm
font-matching-rule-001 Ahem Font Matching Algorithm, Match Font-Family
  • If font property match then use the font specified by font-family, if font property doesn't match, don't even try to match font-family.
font-matching-rule-006 Ahem Font Matching Algorithm, match font-style
  • If the font contains definition of 'italic' or 'oblique' and italic or oblique is set by the style, then use that font.
font-matching-rule-009 = Invalid Font Matching Algorithm, font-weight out of range
  • Invalid font weight values are set to the default weight of 400.
font-matching-rule-010 Font Font Matching Algorithm, font-variant never fails if property does not match
  • If a font property value is not defined, user agent still can use normal value of that property.
font-matching-rule-012 Ahem Font Matching Algorithm, font-size and rounding
  • The font-size for scalable fonts are rounded to the nearest whole pixel.
font-matching-rule-014 Font Font Matching Algorithm, same fonts
  • If all available fonts are exactly same in all properties, the user agent selects one of them.
font-style-rule-001 Font Font-style with font properties missing
  • When font-style italic is not available, find value oblique, if it's still not available, either use the alternate font-family that has italic or oblique value or use 'font-style: normal'.
fonts-010 = Ahem font inheritance into <pre> elements
fonts-011 = Ahem Fonts and bidi
fonts-012 = Ahem Fonts and not bidi
fonts-013 = Ahem font and fallbacks
fonts-014 = Ahem font and fallbacks
