Hi @fazzio349, Codeacademy and many other site use this plugin to create that banner https://meta.discourse.org/t/branding-custom-brand-header-with-logo-navigation-and-icons/53265
.
Unfortunately the plugin is currently broken on the latest versions of Discourse.
@vinothkannans will turn it into a theme when he will have time, in this way it will be much more stable and can be added to the site customizations directly from the administrative panel.
