Deprecated: This feature is no longer recommended.

The fontsize() method creates a <font>
HTML element that causes a string to be displayed in the specified font size.
Syntax
fontsize(size)
Parameters
size-
An integer between 1 and 7, a string representing a signed integer between 1 and 7.
Return value
A string containing a <font> HTML element.
Description
When you specify size as an integer, you set the font size of str to one
of the 7 defined sizes. When you specify size as a string such as "-2", you
adjust the font size of str relative to the size set in the
<basefont> element.
Examples
Using fontsize()
The following example uses string methods to change the size of a string:
var worldString = 'Hello, world';
console.log(worldString.small()); // <small>Hello, world</small>
console.log(worldString.big()); // <big>Hello, world</big>
console.log(worldString.fontsize(7)); // <font size="7">Hello, world</font>
With the element.style object you can get
the element's style attribute and manipulate it more generically, for
example:
document.getElementById('yourElemId').style.fontSize = '0.7em';
