ROAM has recently launched a new component within the page builder - the Image Overlay in the header page builder component section. It offers users ability to include a graphic to float over the hero image which positions correctly with different devices.
This is an additional feature that can be added to any ROAM platform. The purpose of this component is to add additional opportunity to showcase your brand or product. It is especially useful in campaign lander pages for products/services that have their own logo.
To add an Image Overlay to your hero header image, simply upload a transparent .png file. The overlay image will then appear over your header image.
