Fixed-position scrollable area whose contents 'sticky'-scroll along with the document.
This is a progressive enhancement specifically useful for sidebars that are taller than the browser window but want to remain visible/fixed/stuck/onscreen even with very long page content.
Demo:
Example Code (with default options):
$('#sidebar').stickyscroll({
fixedTop: 0, // height to stick top tom, e.g. 44 (px)
fixedBottom: 0, // these can also be selectors, e.g. '#footer, #fixed'
});
