// Sticky Plugin v1.0.0 for jQuery // ============= // Author: Anthony Garand // Improvements by German M. Bravo (Kronuz) and Ruud Kamphuis (ruudk) // Improvements by Leonardo C. Daronco (daronco) // Created: 2/14/2011 // Date: 2/12/2012 // Website: http://labs.anthonygarand.com/sticky // Description: Makes an element on the page stick on the screen as you scroll // It will only set the 'top' and 'position' of your element, you // might need to adjust the width in some cases.
