Values

normal

- : 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>

Keyword	Standard defining the glyphs	OpenType equivalent

`jis83`	JIS X 0208:1983	`jp83`
`jis90`	JIS X 0208:1990	`jp90`
`jis04`	JIS X 0213:2004	`jp04`
`simplified`	None, use the simplified Chinese glyphs	`smpl`
`traditional`	None, use the traditional Chinese glyphs	`trad`

<east-asian-width-values>

  - proportional-width activating the set of East Asian characters which vary in width. It corresponds to the OpenType values pwid.
  - full-width activating the set of East Asian characters which are all of the same, roughly square, width metric. It corresponds to the OpenType values fwid.
