there any way to have support IE animation in html??
IE 10+ supports most of the CSS3 animations, and animations created and exported with Animator 1.5 should work with IE10+.
Older versions of IE simply don't support any CSS3 animation properties.
can not do anything with previous versions?
Pre-10 versions of IE do not support CSS3 keyframe animation. To check CSS support across browsers you can always refer to http://caniuse.com/
And for keyframe animation specifically:
Whether Sound is supported in IE
would like to use Sencha Animator for creating ecard animation with sound. but it doesnt work on IE 11. is this valid?
Sencha Animator does not provide tools for embedding sounds, as there is no way to synchronise audio with keyframe animations in HTML5 spec at this moment.
