Little Car with Shadow

Web Dev is hard on the moral fiber: I've been picking stuff
from varied sources. Below, my little car now has a
shadow, of sorts. I'm running Russian JavaScript code, but on the
div instead of the image (it tags along). The div itself
is a linear gradient with color at the bottom only.  I need
to decide how to animate the shadow.

Some people use CSS animation, and proffer a simple color- block
alternative for Edge. Hope it doesn't come to that...

Finally settled on this view: the problem is getting a drop shadow in front of the

car. I copied the image, put a Gaussian blur on it, squished it to fit between the wheels...
