About the standard theme and custom themes in Help Center

You can use the standard theme that comes with Guide for your Help Center or you can customize the standard theme or create your own theme.

• Standard theme is the Copenhagen theme that comes with Guide. It's a theme designed for best practices and responsiveness (see Using the standard Copenhagen theme in Help Center). You can update the branding settings in the user interface but you cannot edit the code to customize the theme. Otherwise, it will no longer be considered a standard theme.

  When you use the standard Copenhagen theme for your Help Center, it is supported by Zendesk and automatically updated when new theme features are released.

  Note: Before November, 2016, Help Center contained five standard themes. If you are using one of these legacy themes, you can continue to do so, but you will not receive theme updates. If you switch your theme, you will not be able to switch back to the legacy theme.
• Custom theme (Guide Professional) is a theme that you modified by editing the page templates, CSS, or JavaScript. Or, it is any theme that you developed from scratch. These themes are saved as custom themes.

  When you create a custom theme, you take ownership of the theme. Custom themes are not supported by Zendesk and are not automatically updated when new theme features are released. You will continue to receive Guide featuers that are not theme-dependant, but you will not receive updates to your theme, as any update would overwrite your customizations. You can manually add new theming features. To stay informed about new theme features and to get instructions for adding them, subscribe to Zendesk announcements.
