It looks like it’s already low from my end…. If you’re trying to push it even more to the bottom of your header section, then you’ll actually need to reduce the padding of the widget area in the header from this –
.header-image .site-header .widget-area {
padding: 20px 0;
padding: 1.25rem 0;
}
and reduce it to this –
.header-image .site-header .widget-area {
padding: 18px 0;
padding: 1.125rem 0;
}
That will move it down since the widget area has extra padding which makes the height of the header taller. And don’t forget you have space at the bottom of your logo in your actual image itself – http://shoutabrand.com/wp-content/uploads/2014/02/ShoutaBRAND.com_.png
