font-size Attribute | fontSize Property

Sets or retrieves the size of the font used for text in the object.

Syntax

HTML { font-size: sSize }

Scripting object.style.fontSize [ = sSize ]

HTML	{ font-size: sSize }
Scripting	object.style.fontSize [ = sSize ]

Possible Values

sSize String that specifies one of the following values:

absolute-size Set of keywords that indicate predefined font sizes. Possible keywords include [ xx-small | x-small | small | medium | large | x-large | xx-large ]. Named font sizes scale according to the user's font setting preferences.

relative-size Set of keywords that are interpreted as relative to the font size of the parent object. Possible values include [ larger | smaller ].

length Floating-point number, followed by an absolute units designator (cm, mm, in, pt, pc, or px) or a relative units designator (em or ex). For more information about the supported length units, see CSS Length Units.

percentage Integer, followed by a %. The value is a percentage of the parent object's font size. In Internet Explorer 3.0, the value is calculated as a percentage of the default font size.

The property is read/write with a default value of medium; the cascading style sheets (CSS) attribute is inherited.
Expressions can be used in place of the preceding value(s), as of Microsoft® Internet Explorer 5. For more information, see dynamic properties.

Remarks

Negative values are not allowed. Font sizes using the proportional "em" measure are based on the font size of the parent object.

Possible length values specified in a relative measurement, using the height of the element's font (em) or the height of the letter "x" (ex), are supported in Internet Explorer 4.0 and later.

Example

The following examples use the font-size attribute and the fontSize property to change font characteristics.

This example sets the font size on several paragraphs using different size values.

   BODY{font-size: 10pt }
   .P1 {font-size: 14pt }
   .P2 {font-size: 75% }
   .P3 {font-size: xx-large }
   .P4 {font-size: larger }
</STYLE>
