Question

When I click on a element to slideToggle some other elements, I also change the background color of the element that I clicked on to indicate that this is the selected. But how do I remove the background color when I click and slideToggle back the elements?

$(".c756:eq(0)").click(function(){
    $(".c756:eq(0)").css('background-color','yellow');
    $("#wrapper_datorpaket").slideToggle();
});

You could use the toggle method:

$('.c756:eq(0)').toggle(function () {
    $(this).css('background-color', 'yellow');
}, function () {
    $(this).css('background-color', 'transparent');
}).click(function () {
    $('#wrapper_datorpaket').slideToggle();
});
