The Cascading Style Sheets (CSS) Working Group has published a Working Draft of CSS Fonts Module Level 3 . This specification describes how font properties are specified and how font resources are loaded dynamically. Font resources may be local, installed on the system on which a user agent is running, or downloadable. For local font resources descriptive information can be obtained directly from the font resource. For downloadable font resources (sometimes referred to as web fonts), the descriptive information is included with the reference to the font resource. Families of fonts typically don't contain a single face for each possible variation of font properties. The CSS font selection mechanism describes how to match a given set of CSS font properties to a given font face. Learn more about the Style Activity .
