Right now, I seem to be able to apply translate and translate3d, on a group inside a SVG, using px but not using percentages. I'm wondering if it's at all possible to use %? The reason I need them, is because I want to animate the content of several SVG's via CSS. (Using a JS library such as snap or svgjs is giving me a whole bunch of other headaches such as scaling issues in Chrome, so I'd rather avoid using those.)
I created a fiddle to illustrate the behavior: http://jsfiddle.net/f4MU3/4/
CSS:
.cloud-svg .group {
-webkit-transform:translate3d(50%,50%,0);
-moz-transform:translate3d(50%,50%,0);
transform:translate3d(50%,50%,0);
}
HTML:
<div class="container">
<div class="cloud">
<svg class="cloud-svg" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" version="1.1" x="0px" y="0px" viewBox="0 0 107.4 50.6" enable-background="new 0 0 107.4 50.6" xml:space="preserve" preserveAspectRatio="xMinYMin meet" width="100%" height="100%">

(this is somewhat related to this question but that can't be used for animation.)
Strangely enough, I've sometimes seen it work with percentages in Chrome and Safari but not in Firefox. Can't seem to be able to recreate it though.
