Considering that in firefox the position-y doesn't work I need to write a bit of code in jquery to be able to set the background-position-y when hasClass 'no-event'.
what I am doing wrong?
CSS
#products-events .nav li.no-event a:after{background-position-y:-67px;}
Jquery
if ($('#products-events li').hasClass('no-event')) {
//$('.no-event').css('background-position','-67' + yposition );
}
FIDDLE
