Is it possible to animate the transition between background-size: contain and background-size: cover?
css, css-transitions
Solution
It's just not supported - list of properties you can animate
Problem
I know it's possible to animate the transition between `background-size` when using pixel or percentage values using css3, but I can't get it working to animate between `contain` and `cover`. (I'm using webkit - chrome and safari) I have made a fiddle here: http://jsfiddle.net/59Bhb/3/ that shows it working for percentage values, but not contain/cover. Is it just not supported?
