aboutjquery

hello, thanks for this awesome GSAP i have one question, a simple code as below var tl = new TimelineLite(); TweenMax.set($a, {autoAlpha: 0, display: 'none', top: 100}); tl.staggerTo($a, 1, {autoAlpha: 1, top: 0, display: ''}, 0.2); tl.play(); staggerFrom seem better for my code but i cant get it work, i will try again late so now i set the $a property by TweenMax first. if i set the property by css file not by TweenMax, and then play with TimelineLite, will i get the nice performance from gsap too? e.g set translate, opacity, z-index, scale etc any different between set property from css / TweenMax? which one is better? sorry for my language skill, thanks so much
