I am trying to achieve an effect I saw recently, where background image zooms on hover. I pretty much did it with example here: https://jsfiddle.net/qyh6nbwt/ but it seems t
just use transform, scale.
so just instead of setting the bg image to 160% use
transform:scale(1.5);
some information about the transform css property you can find here
to use the transform scale in your case you will need a wrapper with overflow hidden so just the inner div gets bigger and cut of by the outer div.
see updated fiddle.
