The relative keyword ’wider’ sets the value to the next expanded value above
the inherited value (while not increasing it above ’ultra-expanded’); the relative
keyword ’narrower’ sets the value to the next condensed value below the inherited
value (while not decreasing it below ’ultra-condensed’).
15.2.4 Font size: the ’font-size’ and ’font-size-adjust’
properties
’font-size’
Value: | | | |
inherit
Initial: medium
Applies to: all elements
Inherited: yes, the computed value is inherited
Percentages: refer to parent element’s font size
Media: visual
This property describes the size of the font when set solid. Values have the
following meanings:
An keyword refers to an entry in a table of font sizes
computed and kept by the user agent. Possible values are:
[ xx-small | x-small | small | medium | large | x-large | xx-large ]
On a computer screen a scaling factor of 1.2 is suggested between adjacent
indexes; if the ’medium’ font is 12pt, the ’large’ font could be 14.4pt.
Different media may need different scaling factors. Also, the user agent
should take the quality and availability of fonts into account when computing
the table. The table may be different from one font family to another.
Note. In CSS1, the suggested scaling factor between adjacent indexes
was 1.5 which user experience proved to be too large.
A keyword is interpreted relative to the table of font sizes and
the font size of the parent element. Possible values are:
[ larger | smaller ]
For example, if the parent element has a font size of ’medium’, a value of
’larger’ will make the font size of the current element be ’large’. If the parent
element’s size is not close to a table entry, the user agent is free to interpo-
