Touch screen

I cleaned my touch screen while viewing a website and the magnification became huge as I cleaned the screen. However I cannot reduce it back to normal and it is now locked on this huge magnification where only a small section of the screen is visible unless I scroll around it.

It only happens on the one website and other websites are perfectly normal. I am using the Edge browser. When I accessed the website using a different browser it looked normal, so this problem appears to be with the edge browser. Does anyone have an idea what the problem is please?
