_HelloWorld_

I am trying out the gsap animation library. According to the basic docs the syntax for getting a tween up and running is: TweenLite.to( [target object], [duration in seconds], [destination values] ) So I have tried a really simple tween based on jQuery's hover event: $('.contact-item').hover(function(){ TweenLite.to(this,4,{background:'#671B4B'}); },function(){ TweenLite.to(this,4,{background:'#FFFFFF'}); }); Oddly, the background does change to the correct color, but it tweens instantly instead of over the course of 4 seconds as I have specified in the second argument. I did check to make sure the default is seconds not milliseconds. It's in the docs I linked to. I did make sure I am using TweenLite and not TweenMax. I am using jQuery but see no conflicts or errors in the console. Any help is appreciated. I have linked to a codepen I have added the css plugin and it is added to the codepen as well.
