get rid of templating code or paste rendered result is. first problem. 

 function mainbackgroundcolorchange(event) { $(".background-color-features").css({     "background-color": $(event.target).css('background-color'),     "color": $(event.target).css('color') });

}

the target being elements class .background-color-features, don't exist until template code has run, why getting cannot read property 'target' of undefined, templating code rendering properly? lets see result.
