Quicktips is a very lightwight JS funciton that dynamically adds tooltips to html elements. They are automatically positioned below and centered horizontally based on width of the tooltip and parent element. Simply add the JS to your project or page, adjust your markup accodingly, thats it.
Step one (only step really): Add a data-qt attribute to any element you want a tooltip on.
<a href="#" data-qt="Tooltip Label Here">Link Text</a>Include the Javascript in your page or add it to your external JS file.
