Thanks guys. I appreciate your help and suggestions. I was fairly sure I was not dealing with GSAP issue as well, but wasn't convinced that I was dealing with an svg scaling in ie11 problem either. I didn't know if there was something that GSAP could offer that could alleviate this. I think this is a scaling problem now in ie that seems to involve aspect ratio. I had already tried the width: 100%, display: block, and a lot of configurations of preserveAspectRatio (xMidYMid, xMaxYMax, meet, slice, etc.) with no success. http://codepen.io/jstafford/pen/ONeEwZ . This codepen shows width: 100%, max-width: 100%, and display: block using the svg css selector with no success. The preserveAspectRatio configurations work at some widths and not others. I haven't tried the canvas technique yet, but was hoping for a css fix. I will keep plugging away at this.
