    Window.resizeBy()

    Summary

    Resizes the current window by a certain amount.

    Syntax

    window.resizeBy(xDelta, yDelta) 
    

    Parameters

    • xDelta is the number of pixels to grow the window horizontally.
    • yDelta is the number of pixels to grow the window vertically.

    Example

    // shrink the window 
    window.resizeBy(-200, -200);
    

    Notes

    This method resizes the window relative to its current size. To resize the window in absolute terms, use window.resizeTo.

    Since Firefox 7, it's no longer possible for a web site to change the default size of a window in a browser, according to the following rules:

    1. You can't resize a window or tab that wasn’t created by window.open.
    2. You can't resize a window or tab when it’s in a window with more than one tab.

    Specification

    DOM Level 0. Not part of specification.
