How to adjust a background image for all devices
To make sure a background image displays correctly across devices, you can adjust its position manually. Go to the settings of the cover block, then open background image positioning and choose how the screen should be focused relative to the image.
The position of the background image elements will be adjusted based on the selected focus area.
If the available focus options do not work for your image, you can set a custom focus point. To do this, click the icon, drag the focus point to the most important part of the image, and save the settings. This point will be used as the main focus area of the image.
If you need to set a different focus area for the mobile version, duplicate the cover block, set the visibility range for mobile devices, move the focus point to the desired position, and save the changes.
