    Recliner is a super lightweight (1KB) jQuery plugin for lazy loading images, iframes and other dynamic (AJAX) content. Being lazy never felt so good, just hook it up, and start sippin' those margaritas!

    The script was born out of necessity when one of our clients came to us with massive scroll lag on one of their media heavy mobile news sites. It turned out that lazy-load-xt was the culprit, so naturally we tested the other lazy load scripts out there but none of them met our simple criteria:

    • Lightweight
    • Sets stateful CSS classes on elements
    • Ability to override event callbacks for custom behaviour
    • Can load any dynamic content (images, iframes, AJAX)
    • Mobile friendly
    • Printer friendly

    Recliner is currently used on some very high traffic sites, so it's well tested and production ready.


    For more information and a live demo see the project page:


    If you use bower then type:

    bower install recliner

    Or if you like using npm then go ahead and type:

    npm install jquery-recliner

    Otherwise, just download recliner.min.js and stick it in your assets folder :)


    Add jQuery (2.x or 1.x) and Recliner to your HTML source:

    <script src="//"></script>
    <script src="recliner.min.js"></script>

    Bind Recliner on elements with the .lazy class:

        attrib: "data-src", // selector for attribute containing the media src
        throttle: 300,      // millisecond interval at which to process events
        threshold: 100,     // scroll distance from element before its loaded
        printable: true,    // be printer friendly and show all elements on document print
        live: true          // auto bind lazy loading to ajax loaded elements

    You can also progrmatically trigger an update to check for new elements to be loaded:


    Recliner can be used to load a range of different dynamic content.


    Note: It's a good idea to specify image dimensions explicitly so your page height doesn't go berserk as lazy content is loaded into the DOM.

    <img src="some-placeholder-image.png" data-src="image-to-lazy-load.png" class="lazy" width="333" height="333" /> 
    <iframe data-src="" width="333" height="333" class="lazy" frameborder="0" vspace="0" hspace="0"></iframe>
    <div data-src="" class="lazy" style="width:333px;height:333px">
        Loading, be patient damnit!

    Callback API

    Recliner exposes a simple event based API so you can implement your own custom behaviour using callbacks:


    The lazyload event will be triggered on elements that are about to be loaded.

    $(document).on('lazyload', '.lazy', function() {
        var $e = $(this);
        // do something with the element to be loaded...
        console.log('lazyload', $e);

    The lazyshow event will be triggered on elements after they have been loaded.

    $(document).on('lazyshow', '.lazy', function() {
        var $e = $(this);
        // do something with the loaded element...
        console.log('lazyshow', $e);

    Styling and Animations

    Recliner will set the following stateful CSS classes on your elements:

    • lazy-loading: Set while the element is being loaded
    • lazy-loaded: Set when the element has loaded

    Using the stateful classes you can add some fancy transitions to your images:

    img {
      opacity: 0;
      transition: opacity .333s ease-in;
    img.lazy-loaded {
      opacity: 1;
