You can customize the background of your store by changing its color and by adding a background image. We recommend only changing the background color.
Check the “Dark background” setting if the background is of a dark tone (ex: black, dark grey, burgundy, forest green, etc.). This makes sure the borders on top of the element’s background color are the right color. Leave the option unchecked if you’re more on a light background (ex: white, beige, cyan, yellow).
