Changing Site-Title font

Hi,

I am flummoxed. The CSS for Yoko doesn’t have a Font item for site-title H1. Here’s the default:

/* Header
——————————————— */
#site-title {
padding: 21px 0 15px;
}
#site-title h1 {
margin: 0 10px 0 0;
font-size: 2.1em;
line-height:1.2;
font-weight: bold;
text-transform:uppercase;
display: block;
float: left;
}
#site-title h1 a:hover {
text-decoration:none;
}
#site-title h2 {
font:italic .9em ‘Droid Serif’, Times, serif;
color: #777;
margin: 17px 0 0 0;
}
header#branding img.headerimage {
width: 100%;
height: auto;
margin-top: 12px;
}
header#branding img.attachment-headerimage.wp-post-image {
width: 100%;
height: auto;
}
hgroup#site-title img {
max-width: 100%;
}

Adding a Font item to H1 doesn’t do anything.

How do I change the site-title H1 font?

(Note: site-item H2 is easily changed with CSS.)

Thanks,
Peter
