In the WYSIWYG Editor, resize the logo to 105px wide. If that’s not what you’re looking for, navigate to Online Store > Themes > “…” > Edit Code. Find the Asset file titled either “rt.style.scss” or “rt.global.scss” and click to open. Scroll all the way down to the bottom till there is no more code left. Make a new line break and then add:
#header_nav {
padding-top: 48px;
}
You may beed to add !important, so it would be…
#header_nav {
padding-top: 48px !important;
}
