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.

Try it

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.

Constituent properties

This property is a shorthand for the following CSS properties:

Syntax

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:
    • it may optionally include values for:
      • 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.

      Values

      System font values

      The system font used in dialog boxes.

      The system font used for labeling small controls.

      The system font used in window status bars.

      Prefixed system font keywords

      Browsers often implement several more, prefixed, keywords: Gecko implements -moz-window , -moz-document , -moz-desktop , -moz-info , -moz-dialog , -moz-button , -moz-pull-down-menu , -moz-list , and -moz-field .
