Sticky

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". Check the example-*.html files for some examples.

Usage

• Include jQuery & Sticky.
• Call Sticky.

<script src="jquery.js"></script>
<script src="jquery.sticky.js"></script>
<script>
  $(document).ready(function(){
    $("#sticker").sticky({topSpacing:0});
  });
</script>

• Edit your css to position the elements (check the examples in example-*.html).

Options

• topSpacing: Pixels between the page top and the element's top.
• bottomSpacing: Pixels between the page bottom and the element's bottom.
• className: CSS class added to the element and its wrapper when "sticked".
• wrapperClassName: CSS class added to the wrapper.

Methods

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