How to make jump back to big image when click on variants ?

I have a site, when click on a variants, the big image will show variant's big picture, the desktop version got not problems

BUT mobile version, when click on a variants, the big image changed, but client need to scroll up to see what he selected.

Any CSS/JAVA Script/Themes can do this function - When client click on variant, mobile version will jump up to big image let he know his selection

Here is my UAT site, you can try to click with mobile
