3d transition with css (even if it's a 2d move) might help since this may use the GPU. Also make sure it isn't nested in too many elements since chances will cause rerendering the DOM elements up to the root. It isn't that bad and at least here smooth and only if the page is visible. But may have bad effects on mobile/retina/...
