string.fontsize

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

Syntax

str.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> tag.

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</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';
