Hello, please open site1 and site2 with an iPhone.

When you open site1 you can see that the browser shows the site in full width, however if you open site2 you will see that the iphone browser "zooms" up on the top-left corner.

I'd like that:
  • a users opens up the website via iPhone
  • this user will see the website with full width


I think something needs to be edited in the css or html. But I don't know what.
Can anybody help?
Thanks
