The [Theme designer](https://help.staticso2.com/scheduleonce/customization-branding/theme-designer/introduction-to-theme-designer "Introduction to the ScheduleOnce Theme designer") allows you to fully customize the look and feel of your [Booking pages](https://help.staticso2.com/scheduleonce/event-types-booking-pages/booking-pages/introduction-to-booking-pages "Introduction to Booking pages") and [Master pages](https://help.staticso2.com/scheduleonce/master-pages-resource-pools/master-pages/introduction-to-master-pages "Introduction to Master Pages").

The Theme designer comes with two[ system themes](https://help.staticso2.com/scheduleonce/customization-branding/theme-designer/system-themes "System Themes"). If you need more customization for your theme, you can create a custom theme by duplicating an existing theme and modifying it, or you can create a new custom theme from scratch.

You do not need an assigned product license to create custom themes in the Theme designer. [Learn more](https://help.staticso2.com/account-administration/user-management/user-management-and-seats)

However, you may need to upgrade your plan to apply a custom theme to your page(s).

In this article, you’ll learn about creating a custom theme.

## Creating a custom theme

[Section titled “Creating a custom theme”](#creating-a-custom-theme)

1. Go to **Booking pages** in the bar on the left.

2. On the left, select **Theme designer**.

3. Click the **Create theme** button on the top left corner.

4. In the **Create theme** pop-up, enter a **Theme name** and select a **Base theme** for your new Custom theme. Then click **Create**.

   Note

   **Note** The **Base theme** cannot be changed once the theme is created.

5. Alternatively, you can duplicate an existing theme by clicking the **Duplicate theme** button (Figure 2). ![](https://help.staticso2.com/_astro/duplicate-theme.DaU6yUuX_Z21exPr.gif)Figure 2: Duplicate theme button

### Default theme

[Section titled “Default theme”](#default-theme)

You can set any theme as your default theme, including a system theme. The default theme is automatically applied to all newly created pages, but not to existing pages.

## Previewing and applying a Custom theme

[Section titled “Previewing and applying a Custom theme”](#previewing-and-applying-a-custom-theme)

You can preview a theme on a Booking page or Master page by selecting it from the drop-down menu in the top right of the Theme designer and clicking the **Preview** button (Figure 4). Previewing a theme does not apply the theme to the page.

Once you’re happy with it, you can [apply the theme](https://help.staticso2.com/scheduleonce/customization-branding/theme-designer/applying-theme "Applying a theme ").
