<img class='cardoption' src='http://s32.postimg.org/9vao2t9kl/scc_std.png'/>
In this simple piece of HTML, and accompanying CSS, I have an image with class name 'cardoption'. In the style tag in the head, I have attempted to set the width of this image to 20px.
However, for some reason the image is not resizing. Can someone please explain why?
