String.prototype.fontsize()

Summary

The fontsize() method creates a <font> HTML element that causes a string to be displayed in the specified font size.

Usage note: The <font> element has been removed in HTML5 and shouldn't be used anymore. Instead web developers should use CSS properties.

Syntax

str.fontsize(size)

Parameters

size
An integer between 1 and 7, a string representing a signed integer between 1 and 7.

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> tag.

Examples

Example: 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</fontsize>

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'
