Jquery css function help

[prevuri14]

I am using the following code with the accordion ui function where the links on the accordion should change a picture.

Could anyone tell me why the following code is not working:

$(document).ready(function()
{

$("#title1").click(function()
{
	var option = {
		'background-position' : '0px 0px',
	}
	$("#feature2").css(option);

});
$("#title2").click(function()
{

	var option = {
		'background-position' : '0px -100px';
	}
	$("#feature2").css(option);

});

});

 

Thanks for the help
