    Real Shadow — Module that casts photorealistic shadows of any shape

    Perfect for eye-catching demos and landing pages.
    Works in any browser supporting CSS box-shadow property.

    Real Shadow registers itself as CommonJS module, AMD module or jQuery plugin (it depends on your environment).
    If there is no CommonJS, AMD or jQuery, Real Shadow registers itself in the global namespace.

    What's new




    npm i real-shadow


    bower i real-shadow

    Basic Usage with jQuery

    $(selector).realshadow(); // options are optional
        followMouse: false,   // default: true
        pageX: x,             // x coordinate of the light source
        pageY: y              // y coordinate of the light source
        color: '0,127,255'    // shadow color, rgb 0..255, default: '0,0,0'
        type: 'drop' / 'text' // shadow type

    Basic Usage without jQuery

    realshadow(elements); // options are optional
    realshadow(elements, options); // options example listed above

    To specify different colors for each element, you can use "data-shadow-color" attribute:

    <span data-shadow-color="r,g,b"></span> <!-- values in range 0..255 -->
    <span data-shadow-color="255,0,0">red</span>
    <span data-shadow-color="0,255,0">green</span>
    <span data-shadow-color="0,0,255">blue</span>
    <span data-shadow-color="255,255,0">yellow</span>
    <span data-shadow-color="0,255,255">cyan</span>
    <span data-shadow-color="255,0,255">violet</span>
    <span data-shadow-color="100,100,100">grey</span>

    Inset Shadows

        inset: true // default: false

    Inverse Shadows

        inverse: true // default: false

    Custom Shadow Shape

        type: 'drop'

    Text Shadow

        type: 'text'

    Constant Angle

    If you would like the shadows angle to be constant, specify the 'angle' option, in radians.

        angle: Math.PI / 4

    Update shadows during/after jQuery animations

    // before: apply Real Shadow to elements:
    $(selector).realshadow(/* options, if needed */);
    // update shadows during jQuery animation, i.e. each animation step:
    $(selector).animate(/* animated properties */, {step: $.fn.realshadow.update});
    // update shadows after jQuery animation is over:
    $(selector).animate(/* animated properties */, $.fn.realshadow.update);

    If you update shadows during jQuery animation, you don't need to update shadows after jQuery animation is over.

    Custom shadows length

        length: 5 // default is 7

    CommonJS usage

    var realshadow = require('realshadow');
    realshadow(document.getElementsByTagName('li'), options);

    RequireJS / AMD usage

    require(['realshadow'], function(realshadow) {
        realshadow(document.getElementsByTagName('li'), options);

    Reset Real Shadow

    Real Shadow will release all added elements and remove all its event listeners

    // if you have Real Shadow in the current scope:
    // if you use jQuery:
