The fixed background feature, which is available only for prototypes with the device type set to Desktop (Web), lets you set a fixed background while letting the forefront screen continue to scroll vertically (parallax-type scrolling).
To set your fixed background:
- In InVision, open any screen of your prototype.
- On the right side of the console toolbar (next to the Share button), click the ••• (more) icon.
- Under the Background heading, click Upload New.
- Click the lock icon.
- Click the pink Save button.
