    String.prototype.fontsize()

    Deprecated
    This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. Do not use it in old or new projects. Pages or Web apps using it may break at any time.

    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';
