Website scales up after uploading it

Hi All,

I have been developing websites for quite some time now, but tonight I have come across something that is truly new and strange to me, not to mention annoying because Google has absolutely NO answers on this one!

I have developed a home page on localhost, and everything worked as expected in all browsers tested. I uploaded the website to my server so that my client could look at it from his side. I got a call from him stating that everything is too big, so I went to the live site and could not believe that everything in front of me is zoomed.

This is so irritating! Why did my website zoom in upon uploading it?? It is only zoomed by 1 I think because when I hold Ctrl + Scroll Down (Only Once). It is as it should be.

What could be the cause of this?

Regards,
Chris
