’baseline’ (Descriptor) Value: Initial: 0 Media: visual This is the descriptor for the lower baseline [p. 229] of a font. If this descriptor is given a non-default (non-zero) value, the ’units-per-em’ [p. 218] descriptor must also be used. ’centerline’ (Descriptor) Value: Initial: undefined Media: visual This is the descriptor for the central baseline [p. 227] of a font. If the value is undefined, the UA may employ various heuristics such as the midpoint of the ascent and descent values. If this descriptor is used, the ’units-per-em’ [p. 218] descriptor must also be used. ’mathline’ (Descriptor) Value: Initial: undefined Media: visual This is the descriptor for the mathematical baseline [p. 229] of a font. If undefined, the UA may use the center baseline. If this descriptor is used, the ’units-per-em’ [p. 218] descriptor must also be used. ’topline’ (Descriptor) Value: Initial: undefined Media: visual This is the descriptor for the top baseline [p. 230] of a font. If undefined, the UA may use an approximate value such as the ascent. If this descriptor is used, the ’units-per-em’ [p. 218] descriptor must also be used. 15.3.9 Examples Example(s): Given the following list of fonts: 224
Swiss 721 light Swiss 721 Swiss 721 medium Swiss 721 heavy light & light italic roman, bold, italic, bold italic medium & medium italic heavy & heavy italic Swiss 721 black black, black italic, & black #2 Swiss 721 Condensed Swiss 721 Expanded roman, bold, italic, bold italic roman, bold, italic, bold italic The following font descriptions could be used to make them available for download. @font-face { font-family: "Swiss 721"; src: url("swiss721lt.pfr"); /* Swiss 721 light */ font-style: normal, italic; font-weight: 200; } @font-face { font-family: "Swiss 721"; src: url("swiss721.pfr"); /* The regular Swiss 721 */ } @font-face { font-family: "Swiss 721"; src: url("swiss721md.pfr"); /* Swiss 721 medium */ font-style: normal, italic; font-weight: 500; } @font-face { font-family: "Swiss 721"; src: url("swiss721hvy.pfr"); /* Swiss 721 heavy */ font-style: normal, italic; font-weight: 700; } @font-face { font-family: "Swiss 721"; src: url("swiss721blk.pfr"); /* Swiss 721 black */ font-style: normal, italic; font-weight: 800,900; /* note the interesting problem that the 900 weight italic doesn’t exist */ } @font-face { font-family: "Swiss 721"; src: url(swiss721.pfr); /* The condensed Swiss 721 */ font-stretch: condensed; } @font-face { font-family: "Swiss 721"; src: url(swiss721.pfr); /* The expanded Swiss 721 */ font-stretch: expanded; } 225
