Banner ads: how to keep the file sizes down? in GSAP Posted October 24, 2014 Thank you! I'm still tossing around the various options in my head. I don't much like the animation possibilities built into Edge - very limited, I think. It all boils dowjn to whether I can find the time to do some work with GSAP before this project gets approved and then, well, the race is on... I've now got my understanding of Edge at a point where I could do all of the banners pretty quickly - as long as the client doesn't dream up some complex animation thing.
