Header & Footer
Site-Wide Banner
Currently, BigCommerce’s Banner system only lets you add a banner on a page-by-page basis. Meaning you would have to create a new duplicate banner for every page you want it on. To get around this, a site-wide region has been added above the header that will make the banner appear on all pages. To use it, simply drag a widget (most likely the html widget) into the “Header Top—Global” region (the one right above the main nav). Make sure to change the Header Banner Default height in the Theme Styles if the banner is more than 45px tall.
