Simple catch (site title font change)

Hello, is there an easy way to change the font of the site title, or do I have to do it with the customs css? Or do I have to do it like this. h1 {font-family: adobe-garamond-pro,sans-serif;font-style: normal;font-weight: 400;font-size: 50%;letter-spacing:8px;} Best Lukas
