Syntax

Property values

Type: BSTR

Up to six of the following space-delimited property values. Alternatively, sets or retrieves the six listed text fonts.

font-style (normal)

Any of the range of font-style values available to the IHTMLRuleStyle::fontStyle property.

font-variant (normal)

Any of the range of font-variant values available to the IHTMLRuleStyle::fontVariant property.

font-weight (normal)

Any of the range of font-weight values available to the IHTMLRuleStyle::fontWeight property.

font-size (medium)

Any of the range of font-size values available to the IHTMLRuleStyle::fontSize property. When this value is an integer followed by a percent (%), the value is a percentage of the parent object's font size.

line-height (normal)

Any of the range of line-height values available to the IHTMLRuleStyle::lineHeight property. When used with the IHTMLRuleStyle::font property, this attribute must include a slash (/) before the value. Line height percentage values are calculated as a percentage of the font size of the element itself, not of the parent.

font-family ("Times New Roman")

Any of the range of font-family values available to the IHTMLRuleStyle::fontFamily property. This property can be set to multiple comma-separated values. Its default value depends on user settings.

caption

User-preference font used in objects that have captions—buttons, labels, and so on.

icon

User-preference font used in icon labels.

menu

User-preference font used in menus.

message-box

User-preference font used in dialog boxes.

small-caption

User-preference font used in small controls.

status-bar

User-preference font used in window status bars.

String format

[[ font-style || font-variant || font-weight ]? font-size [ / line-height ]? font-family ]| caption | icon | menu | message-box | small-caption | status-bar

Remarks

This is a composite property that specifies up to six font values. The font-style, font-variant, and font-weight values may appear in any order before font-size. However, the font-size, line-height, and font-family properties must appear in the order listed. Setting the IHTMLRuleStyle::font property also sets the component properties. In this case, the string must be a combination of valid values for the component properties; only font-family may have more than one value. If the string does not contain a value for a component property, that property is set to its default, regardless of prior settings for that component property.

As of Microsoft Internet Explorer 6, when you use the !DOCTYPE declaration to specify standards-compliant mode, the following conditions apply to this property.

The font-size and font-family values must be declared. If font-size and font-family are not declared, or are not in the correct order, the IHTMLRuleStyle::font property is ignored.
All specified values must appear in the correct order. Otherwise, the IHTMLRuleStyle::font property is ignored.
In standards-compliant mode, the default font-size is small, not medium. If not explicitly set, font-size returns a point value.

Examples

This example displays three lines of text using different IHTMLRuleStyle::font settings.

body {
  font: Garamond, serif;
}
.sans-serif {
  font: italic small-caps 12pt Arial, sans-serif;
}
.monospace {
  font: bold 14pt Courier, monospace;
}

<body>
  <p>Lorem ipsum dolor sit amet... (font: Garamond, serif)</p>
  <p class="sans-serif">Lorem ipsum dolor sit amet... (font: italic small-caps 12pt Arial, sans-serif)</p>
  <p class="monospace">Lorem ipsum dolor sit amet... (font: bold 14pt Courier, monospace)</p>
</body>

The following image shows the result. The first line of text shows the default body element IHTMLRuleStyle::font setting that specifies a font from a serif font family. The second line of text shows a IHTMLRuleStyle::font setting that specifies an italic font style, small-caps font variant, 12-point font size, and a font from a sans-serif font family. The third line of text shows a IHTMLRuleStyle::font setting that specifies a bold font weight, 14-point font size, and a font from a monospace font family:
