Previously I wrote two tutorials on how to style the image element with CSS3 inset box-shadow and border-radius. The trick is to wrap the image with a span tag and apply the image as background-image. However, I recently ran into a problem with that trick while designing the PhotoTouch theme. The issue is that the background-image is not resizable and thus it is not a good idea to use in responsive design. Fortunately, I found a workaround to resolve this. So today I’m going to revisit this topic again.
