The animated background requires use of the Custom Code Configuration feature - a feature of our paid plans. This premium feature allows you to insert custom CSS, and comes with two built-in animations:
- Horizontal Zoom
- Vertical Scroll
Both involve selecting a background image and then applying an effect to it. Selecting either option will fill the custom code configuration with the necessary code - you can then change the URL of the background image to anything you'd like.
The Custom Code Configuration can be found at the bottom of the Edit page.
