jQuery-fixedScroll is a jQuery plugin to make areas of the page follow other content while scrolling.
It's similar to other plugins like jQuery-followScroll, but it uses different techniques; for instance, it will make a following block fixed when necessary, so it won't move even when the user scrolls.
It also handles the cases when a box is too tall for the current viewport; it will scroll to the bottom, and then pin it there; if the user then scrolls up, it will also scroll up the box until the top of that box is reached, and then pin it to the top; for instance, some of the the bars at the left of this text should be taller than your viewport; if the document is scrolled down, so will the taller bars. Once the bottom of the area it follows is reached, it will stop there.
Using this plugin is very easy; include both jQuery and this plugin scripts to
your page, then call the fixedScroll() method; to specify the target the block
should be following, use the an options object that contains a follow field;
the value of that field can be either a jQuery selector, or a jQuery object that
contains the block that will be followed:
// Make all blocks with the "moving" class follow the target
$('.moving').fixedScroll( { follow: '#target' } );
// This is also valid
$('.moving').fixedScroll( { follow: $('#target') } );Tested in IE9, Firefox 17 and Chrome 23. Other browsers may work, but haven't been tested. It's a safe bet that anything based on a recent version of Gecko or WebKit will probably work.
