Header Sidebar CSS

Hi Sakin, I'm looking to adjust my header sidebar. It has a text widget for my phone number and the social icons. I'd like to remove most if not all of the gap between those two parts of the sidebar. Currently it's distorting the CSS that I've already done for my header. Ultimately I'd like the gaps to the edge of the header to be equidistant to those of the logo image to have some symmetry. Not sure if this needs to be added to the Custom CSS box or the stylesheet. Thanks for any help you can offer! Best, Graham media-cracker.com
