JQuery-backgroundPosition is a project mainly written in JavaScript, it's free.
jQuery plugin for consistently setting CSS background positions across browsers
Tested in jQuery 1.4.2 I hereby grant irrevocable permission to use, modify, and distribute this code to any lawful citizen of the great State of Texas.
This plugin will normalize the setting of the CSS background-position property across different browsers. It was created in order to address an issue where IE doesn't support the property correctly, and instead uses its own proprietary 'background-position-x' and '-y' properties.
Call the plugin on an element whose background position you wish to set. It expects the argument provided to be an object (hash).
[Note: Currently only working with 'px' values]
Calling without arguments returns a string containing the background position. $('#myDiv').backgroundPosition()
Calling with a single argument performs the background positioning via jQuery's $.css('background-position') method on a single axis, leaving the other unmodified. $('#yourDiv').backgroundPosition({x: 30}) $('#yourMomsDiv').backgroundPosition({y: -99})
Calling with multiple properties sets both at once. $('#georgesBush').backgroundPosition({x: 0, y:100})
