Blog Title size

It looks like you are using an image as your site title, so you can either use an image editor to make it smaller (probably the better way to go) or you can add this rule using Jetpack’s custom CSS option:

.site-branding img {
   width: 80%;
}

Set the percentage to the size that you want. The only problem is that some of the other elements of the header are also going to shrink, because they are part of the same image (like the gray box that fades in and out).

Thanks.
