Sticky is a jQuery plugin that gives you the ability to make any element on your page always stay visible.
This is how it works:
- When the target element is about to be hidden, the plugin will add the class
classNameto it (and to a wrapper added as its parent), set it toposition: fixedand calculate its newtop, based on the element's height, the page height and thetopSpacingandbottomSpacingoptions. - That's it. In some cases you might need to set a fixed width to your element when it is "sticked". Check the
example-*.htmlfiles for some examples.
- 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).
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.getWidthFrom: Selector of element referenced to set fixed width of "sticky" element.
sticky(options): Initializer.optionsis optional.sticky('update'): Recalculates the element's position.
