    Sticky is a jQuery plugin that gives you the ability to make any element on your page always stay visible.

    Sticky in brief

    This is how it works:

    • When the target element is about to be hidden, the plugin will add the class className to it (and to a wrapper added as its parent), set it to position: fixed and calculate its new top, based on the element's height, the page height and the topSpacing and bottomSpacing options.
    • That's it. In some cases you might need to set a fixed width to your element when it is "sticked". But by default (widthFromWrapper == true) sticky updates elements's width to the wrapper's width. Check the example-*.html files for some examples.


    • Include jQuery & Sticky.
    • Call Sticky.
    <script src="jquery.js"></script>
    <script src="jquery.sticky.js"></script>
    • Edit your css to position the elements (check the examples in example-*.html).

    • To unstick an object



    • topSpacing: (default: 0) Pixels between the page top and the element's top.
    • bottomSpacing: (default: 0) Pixels between the page bottom and the element's bottom.
    • className: (default: 'is-sticky') CSS class added to the element's wrapper when "sticked".
    • wrapperClassName: (default: 'sticky-wrapper') CSS class added to the wrapper.
    • center: (default: false) Boolean determining whether the sticky element should be horizontally centered in the page.
    • getWidthFrom: (default: '') Selector of element referenced to set fixed width of "sticky" element.
    • widthFromWrapper: (default: true) Boolean determining whether width of the "sticky" element should be updated to match the wrapper's width. Wrapper is a placeholder for "sticky" element while it is fixed (out of static elements flow), and its width depends on the context and CSS rules. Works only as long getWidthForm isn't set.
    • responsiveWidth: (default: false) Boolean determining whether widths will be recalculated on window resize (using getWidthfrom).
    • zIndex: (default: inherit) controls z-index of the sticked element.


    • sticky(options): Initializer. options is optional.
    • sticky('update'): Recalculates the element's position.


    • sticky-start: When the element becomes sticky.
    • sticky-end: When the element returns to its original location
    • sticky-update: When the element is sticked but position must be updated for constraints reasons
    • sticky-bottom-reached: When the element reached the bottom space limit
    • sticky-bottom-unreached: When the element unreached the bottom space limit

    To subscribe to events use jquery:

      $('#sticker').on('sticky-start', function() { console.log("Started"); });
      $('#sticker').on('sticky-end', function() { console.log("Ended"); });
      $('#sticker').on('sticky-update', function() { console.log("Update"); });
      $('#sticker').on('sticky-bottom-reached', function() { console.log("Bottom reached"); });
      $('#sticker').on('sticky-bottom-unreached', function() { console.log("Bottom unreached"); });
