Padding Not Displaying on Mobile

Hello -

I am using Screens and have developed the following site - For some reason on mobile (iPhone 4 and 5 for example) the column padding is not working on the last screen (with the contact form). As such, the footer and ‘Send’ button are overlapping. When I apply padding in Rapidweaver to the column holding the ‘Send’ button, the padding is displaying when previewing in Rapidweaver, however, the padding will not display when I publish to my site. I am exporting all files and then uploading using CyberDuck.

I am at a loss here as to why the padding is not displaying on the website. Any insight would be greatly appreciated.

Much appreciated!
