I've created a custom header in photoshop and uploaded it to the yoko theme to serve as the blog's header. Right now the header isn't clickable to redirect to the blog's homepage. I just switched from the 2011 theme, whose header was clickable, to yoko, and I'd like to keep the header clickable - is this something I can do in the css customization? Also having difficulties finding the correct code.
