By default, the section background images are set to cover the entire area.
You can change this for specific sections by giving that section a custom class.
Then, with the custom class, do this:
.generate-sections-container.my-custom-class {
background-size: auto;
background-position: center center;
}
That will remove the cover attribute, and set the background image to show up in the very center of the area.
Hope this helps π
