background image area too small

hi everyone,

i’m trying to enlarge my background container so the image fits. right now
i have:

.site-header h1 a {
background-image: url(https://www.waynecina.com/wp-content/uploads/2014/12/logo.jpg);
background-size: contain;
background-repeat: no-repeat;
color: transparent;
line-height: 100px;
}

please see: https://www.waynecina.com
the image is 486px x 112px but it’s not showing up that way

thank you!
