Animate css in background size?

Question

I am trying to animate the size of my background image, but it does not work. Any idea why from the following code?

$(this).animate({'opacity' : 1, 'background-size':'70px 48px', 'right':39, 'top':45}, 250);

Note. All other properties are animated correctly, it's just the size of the background, which is not updated.

Thank!

Answer 1

Because it background-sizeis a CSS3 property that is not supported by jQuery, but is still a candidate for recommendation .
