Responsivness Issue

Hi,

I’m trying to align a form made with CoffeCup Web Form Builder.

I have centered the div using provided code, it works really well but as soon as the responsiveness hits smaller level the form is not centered anymore. I tried the code on a different template and it works 100% on all screen sizes.

Below is a link with an example. It displays perfectly on normal size screen but moves to the right on smaller screens – Issue starts as soon as the search bar drops to the bottom of the screen:

Any help will be greatly appreciated… ??

Thanks in advance!
