css for tagline

I’m working on customizing this new theme. I can’t figure out how to fully separate the title blog and tagline (for example, when I make the title bigger, the tagline gets bigger as well). Any advice on how to customize the tagline?

Here’s my header css, if that helps:

/* HEADS */

div#content h1{
	margin-bottom: 8px;
	padding-bottom: 8px;
}

div#content h1.listhead {
	font-size: 0.85em;
	text-transform: uppercase;
	background: #f8f8f8;
	border: 1px dotted #d1d1d1;
	margin: 0 0 20px 0;
	padding: 10px !important;
}

ul#sidebar h2, div.nav{
	font-size: 1em;
	text-transform: uppercase;
	font-weight: bold;
}

ul#sidebar h2 {
	margin-bottom: 10px;
}

#header {
	margin-bottom: 10px;
	border-bottom: 1px dotted #d1d1d1;
}

h1.blog-title {
	font-size: 1.5em;
	padding: 40px 0 20px 0;
}

h1.blog-title a:link, h1.blog-title a:active, h1.blog-title a:visited{
	border-bottom: none;
}

h1.blog-title a:hover {
	border-bottom: none;
}

Thanks!
