password page background optimized for mobile and desktop

How do I make my password page background optimized for mobile and desktop view. Desktop view looks perfect but the second I switch to Mobile view it is out of crop.

There is no option to separate the two views. The only option I have is “background image” in the theme editor. Is there something in the coding that I need to edit/change? Ive searched so many discussions just to find no working result.

theme is “prestige” and website is blackoutlabz.com password is: blackout24

Hello @llarsfrederick ,

If you are good with code then you can create an option image for mobile.

And call it a/to the device with media query width css.

Thanks
