An ad format consists of two panels – main and expanded. The main panel appears on a page-load in a content zone that is 100% of a site width. On a page scroll, an ad container becomes larger in size and an expanded panel appears. The expanded panel can contain video. Video playback starts automatically when the banner reaches the user’s viewport.
This ad format may be subject to restrictions imposed by

Coalition for Better Ads on delivery of ads in Chrome. List of ad experiences that should be avoided in this ad format according to

- Placement: video player container is placed in the center of the expanded panel and occupies 50% of the expanded panel’s height in portrait device orientation and 70% of the expanded panel’s height in landscape orientation. Video player container width is calculated based on the video file aspect ratio. In this case, the expanded panel serves as a background, so it is recommended that the background shouldn’t contain any important information.
Having a video in the banner makes the expanded panel file non-obligatory. The background may be set as a color in the template in the user interface.
Background (optional)
The banner background sets as a color in the creative template in the user interface. Background fills the empty space that may remains while images are being scaled.
Template Settings
The template settings are available in the UI.
- Background color — you can choose a button color in the additional color window or enter a color code.
