image border

Hi There,

I want 1 image that I have with a border and a bit rotated. If found out the following code will do what I want when I paste it into the quick css. Only it affects all images. How can I set it so that it only afeects one image?

1img{ box-shadow: 0 0 10px black, 0 0 0 0px gray;
padding: 10px; transform:rotate(3deg)}
