The font-variant-east-asian CSS property controls the usage of alternate glyphs for East Asian scripts, like Japanese and Chinese.

font-variant-east-asian: jis78;              /* <east-asian-variant-values> */

font-variant-east-asian: jis90;              /* <east-asian-variant-values> */
font-variant-east-asian: jis04;              /* <east-asian-variant-values> */
font-variant-east-asian: simplified;         /* <east-asian-variant-values> */
font-variant-east-asian: traditional;        /* <east-asian-variant-values> */
font-variant-east-asian: full-width;         /* <east-asian-width-values> */

Syntax

Values

normal
This keyword leads to the deactivation of the use of such alternate glyphs.
ruby
This keyword forces the use of special glyphs for ruby characters. As these are usually smaller, font creators often designs specific forms, usually slightly bolder to improve the contrast. This keyword corresponds to the OpenType values ruby.
<east-asian-variant-values>
These values activate the figures defined in specific standard. Possible values are:
Keyword Standard defining the glyphs OpenType equivalent
jis78 JIS X 208 version 1978 jp78
jis83 JIS X 208 version 1983 jp83
jis90 JIS X 208 version 1990 jp90
jis04 JIS X 208 version 2004 jp04
simplified None, use the simplified Chinese glyphs smpl
traditional None, use the traditional Chinese glyphs trad
<east-asian-width-values>
These values control the sizing of figures used for East Asian characters. Two values are possible:
  • proportional-width activating the set of figures where numbers are not all of the same size. It corresponds to the OpenType values pwid.
  • full-width activating the set of figures where numbers are all of the same size, allowing them to be easily aligned like in tables. It corresponds to the OpenType values fwid.

Formal syntax

normal | [ <east-asian-variant-values> || <east-asian-width-values> || ruby ]

where
<east-asian-variant-values> = [ jis78 | jis83 | jis90 | jis04 | simplified | traditional ]
<east-asian-width-values> = [ full-width | proportional-width ]

Examples
