How do I add a favicon to the theme?

The favicon can be added in the Website settings under Pages on the Branding tab or in your account's Brand Kit

To add the favicon to your Brand Kit, open your HubSpot Settings and click Account defaults from the menu on the left sidebar.

Select the Branding tab and the Brand Kit you want to edit (or create a new one).

Scroll to the Favicon section and click +Add, then select an image and add a name.

To add the favicon to your Website settings, click on Pages from the left sidebar and select the Branding tab.

You can configure a Favicon as the default for all domains, or individually select a Favicon per domain.
