This page describes the in-app parallax format: where it should be displayed and the available APIs.

---

## Overview

The in-app parallax is an inline ad which shows part of a full screen ad under the app content during scroll interactions. It supports images, agency scripts and HTML 5 creatives.

This format is designed to be displayed inside a `SASBannerView` attached to _scroll view_. The parallax effect only applies when scrolling vertically.

Note that on iOS the parallax effect will only works on class inheriting from `UIScrollView`.

## Improving parallax rendering in your application

The `SASBannerView` can automatically display parallax of ads when integrated into scrollable view.

The creative displayed inside the parallax banner view will takes the whole screen by default, excluding the navigation bar and the status bar on Android or the app's window safe area on iOS.

It means that part of the creative might be hidden by some elements of your UI, especially elements covering the scrollable view.

You can configure margins for your banner views to avoid this issue, check the [Android banner integration guide](https://help-display-sdk.equativ.com/android/integration/banner.html#parallax) or the [iOS banner integration guide](https://help-display-sdk.equativ.com/ios/integration/banner.html#parallax) for more information.
