+                  Because of the card layout, the image size is not increasing consistently with the device size.
+                  The image sizes are based on the layout on a banner page with wide layout.
+                  The designed image aspect ratio is 16:9.
+
+                  Screen sizes:
+                    small: "576px"
+                    medium: "768px"

+                    "2xl": "1400px"
+
+                  The picture element will use the first source with a matching media query.
+                  Using min-media queries, we need to list the breakpoints in decending order, otherwise larger screens will always use the first listed (because that min-width query would be fulfilled).
