any way to make a space smaller than a label

Is there a way to make a space smaller than the use of a break tag. If you access my site (in sig), you will see an AdSense link unit at the top. I would like to move it a bit, but from now on I can not figure out how. I'm using a
label to get the space, which seems too much, and not
the label is not enough. Any way to do this?
