I have checked the HTML5 Browser Support and I must say I'm not very happy BUT I still want to use HTML5 Animation in my website.
The thing is that I want to target all the browser versions that don't support HTML5 Animation and display only an image of the animation if an older version that the ones supported returns true. 
I am aware of IE Conditional Comments, and by the chart below, only IE9 and higher support HTML5 so that will be fixed with a :
<!--[if lte IE8]>
  <style type=”text/css”>
    IE lower or equal to IE8 Replace animation coding with an image.
  </style>
<![endif]-->
HTML5 Browser Support chart

But how do I target let's say Chrome versions lower than 25 or Opera versions lower than 12 ?
