h2 problem

hi,

have a look at the H2 in the sidebar boxes of this site http://www.assancarlosesto.com/

i get that white space, how to avoid it?

here's the css:

#left_side h2, #right_side h2 {
	height:30px;
	margin: 5px 0 0;
	padding:0px 0px 0px 5px;
	background: url(http://www.assancarlosesto.com/wp-content/themes/san_carlo_sesto/images/header_st.png) repeat-x; 
}

Code (markup):

 

remove it from the image you are calling as a background? The top six or seven pixels are white.
