The navbar header will contain your site logo and the call-to-action button. The logo will be the Site Horizontal Logo, if configured, otherwise the Site Icon alongside the name of the site.
The Call-to-action button is featured not just in the navbar but across the website experience, especially in places where interactivity is not allowed unless the user joins the Slack workspace.The Call-to-action button is typically a link to join your Slack community. See how to configure it here.
The Feed navigation items will display the emoji icon using the Noto Emoji Google font, if any are configured for the Feed (instructions), or falls back to a default icon.
The Noto Emoji Google font has limited support across browsers. We highly
recommend testing your choice of emoji in the Noto Emoji Type
tester within the
major browsers.
