Increase performance of box-shadow

Question

I think it's quite likely the answer is no, but someone might know something I don't.

I've got an image gallery with sorting buttons that, when clicked, sorted the gallery in an animated style using Isotope. Each image has a nice box-shadow around it, but the animation is sluggish and jerky, due to having to render the shadow all the time.

My question is this: Is there a way to speed up box shadow without changing the blur radius, etc?

Answer 1

I suspect there's no way to speed it up.

Have you considered toggling off the box-shadow while the animation is running?

Does the box-shadow use an rgba colour with transparency? Maybe it would be faster without transparency.
