[help] -margins for img tags

i have smilies that i want to fit within my line so i wanted it to have a -2px margin-bottom so it would fit.

here is my tag but it doesn't work:

<img src="../../unavailable.html" height="16" width="16" margin-bottom"-2" />

Well you are missing an equal sign

BTW. your code should actually have the margin-bottom declared as a style

<img src="../../unavailable.html" height="16" width="16" style="margin-bottom:-2;" />
