Working Draft 2012-08-23

Support information:

As of the last update, the working draft was supported as described below:

• The following properties are not supported:
  • font-stretch
  • font-size-adjust
  • font-synthesis
  • font-kerning
  • font-feature-settings
  • font-language-override
• The font-variant property only supports values from CSS 2.1, that is normal or small-caps, and none of the properties whose names begin with font-variant- are supported.
• Opera supports the @font-face rule, except the unicode-range, font-variant and font-feature-settings descriptors.
• Opera supports the following font formats:
  • OpenType (OTF)
  • TrueType (TTF)
  • SVG fonts
  • Web Open Font Format (WOFF)
• As defined in section 4.7 "Font loading guidelines", Opera will avoid a flash of unstyled text and delay rendering text until its fonts are downloaded, but will wait at most 5 seconds.
• Opera does not enforce the same-origin restriction.
• Opera matches its fonts using a different algorithm than specified in chapter 5: the first loadable font in the font-family property is tried; if it does not support a given character, that character is rendered using a the system font fallback procedure or the missing character glyph.
• Opera does not support the @font-feature-values rule.
