Upfront & Keyframes withing Region

Greetings once again,

I'm trying to add text Marquee with CSS3 Keyframe animation in a floating region at my landing page.

I was wondering if Upfront supports Keyframe because the animation won't work.

Basically i have my y height main region. In the main region i placed a floating region where i wanted it. In the floating region i dropped a code Element and started coding it.

Although most of the styling and html works, the keyframes won't activate and so the animation won't kick in.

Normal CSS3 and Marquee animation works fine. Keyframe does not.

Any idea why?
