Best CSS to move Site Title down?

Hi, my CSS skills are limited at best. I’d like to move the MEDATS site title down a little. I figured out how to move the description down with padding.

#site-description {
display: inline;
float: left;
font-size: 1em;
padding: 25px 6px 3px 0;
clear: both;

But if I add padding to this:
#site-title a {
text-decoration: none;
letter-spacing: -0.03em;
display: block;
font-size: 1em;
line-height: 1.1;
}

It moves both the title and site description down. Can someone help?
