Mobile browser width issue with zoom Lightbox Jquery

Hi, I build a small webapplication (suppose for smartphones). In a page there is a simple Lightbox with Jquery. When I close this Lightbox I have set [login to view URL](true); or [login to view URL]();... The page reloads but when the visitor has zoommin to the lightbox to see the picture bigger and when I close the Lightbox... the browser stays in that zoommin stage. My target is when close Lightbox the browser is back to normal width. I talk here over IOS Safari and Android Chrome. I try also with: setTimeout(function(){ [login to view URL] = "#"; },300); But its give me not the good result. My target is let only the lightbox zoomin or zoom out but not the whole page behind. Who can help me trough Teamviewer and Skype? NOTE: I work on a 30" screen. So please be aware that you also work on a big screen. On a default laptop the code renders very (to) small and is unreadible. I can zommin on my screen but the code will be very blury. Thanks in advance. Herman.
