font

The font CSS shorthand property sets all the different properties of an element's font. Alternatively, it sets an element's font to a system font.

As with any shorthand property, any individual value that is not specified is set to its corresponding initial value (possibly overriding values previously set using non-shorthand properties). Though not directly settable by font, the longhands font-size-adjust and font-kerning are also reset to their initial values.

This property is a shorthand for the following CSS properties:

• font-family
• font-size
• font-stretch
• font-style
• font-variant
• font-weight
• line-height

The font property may be specified as either a single keyword, which will select a system font, or as a shorthand for various font-related properties.

If font is specified as a system keyword, it must be one of: caption, icon, menu, message-box, small-caption, status-bar.

If font is specified as a shorthand for several font-related properties, then:

• it must include values for:
  • <font-size>
  • <font-family>
• it may optionally include values for:
  • <font-style>
  • <font-variant>
  • <font-weight>
  • <font-stretch>
  • <line-height>
• font-style, font-variant and font-weight must precede font-size
• font-variant may only specify the values defined in CSS 2.1, that is normal and small-caps
• font-stretch may only be a single keyword value.
• line-height must immediately follow font-size, preceded by "/", like this: "16px/3"
• font-family must be the last value specified.
