font

{{CSSRef}} 

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.

{{EmbedInteractiveExample("pages/css/font.html")}} 

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 {{cssxref("font-size-adjust")}}  and {{cssxref("font-kerning")}}  are also reset to their initial values.

Constituent properties

This property is a shorthand for the following CSS properties:

• {{cssxref("font-family")}} 
• {{cssxref("font-size")}} 
• {{cssxref("font-stretch")}} 
• {{cssxref("font-style")}} 
• {{cssxref("font-variant")}} 
• {{cssxref("font-weight")}} 
• {{cssxref("line-height")}} 

Syntax

/* font-size font-family */
font: 1.2em "Fira Sans", sans-serif;

/* font-size/line height font-family */
font: 1.2em/2 "Fira Sans", sans-serif;

/* font-style font-weight font-size font-family */
font: italic bold 1.2em "Fira Sans", sans-serif;

/* font-stretch font-variant font-size font-family */
font: ultra-condensed small-caps 1.2em "Fira Sans", sans-serif;

/* system font */
font: caption;

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:

  • {{cssxref("<font-size>")}} 
  • {{cssxref("<font-family>")}} 

• it may optionally include values for:

  • {{cssxref("<font-style>")}} 
  • {{cssxref("<font-variant>")}} 
  • {{cssxref("<font-weight>")}} 
  • {{cssxref("<font-stretch>")}} 
  • {{cssxref("<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.

Values

• <'font-style'>
  • : See the {{cssxref("font-style")}}  CSS property.
• <'font-variant'>
  • : See the {{cssxref("font-variant")}}  CSS property.
• <'font-weight'>
  • : See the {{cssxref("font-weight")}}  CSS property.
• <'font-stretch'>
  • : See the {{cssxref("font-stretch")}}  CSS property.
• <'font-size'>
  • : See the {{cssxref("font-size")}}  CSS property.
• <'line-height'>
  • : See the {{cssxref("line-height")}}  CSS property.
• <'font-family'>
  • : See the {{cssxref("font-family")}}  CSS property.

System font values

• caption
  • : The system font used for captioned controls (e.g., buttons, drop-downs, etc.).
• icon
  • : The system font used to label icons.
• menu
  • : The system font used in menus (e.g., dropdown menus and menu lists).
• message-box
  • : The system font used in dialog boxes.
• small-caption
  • : The system font used for labeling small controls.
• status-bar
  • : 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.
