Fix the issue for multiple images on change in zoom

[Priyansh-Kedia]

Please make changes so that only one image is shown on zoom out and zoom in maintaining the size ratio

[kingscode-06]

As the background-size is provided as "contain", it does not repeat on zooming in or zooming out, instead, it is fixed. I can't see this issue through my browser. Please check again if this issue still remains.
