    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.


    The big() method creates a <big> HTML element that causes a string to be displayed in a big font.

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




    The big() method embeds a string in a <big> tag: "<big>str</big>".


    Example: Using big()

    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)); // <fontsize=7>Hello, world</fontsize>

    With the object you can get the element's style attribute and manipulate it more generically, for example:

    document.getElementById('yourElemId').style.fontSize = '2em';
