css input box width

Hi there, I have a very small CSS issue with a form input field I can't seem to fix. When you view the mobile site on your iphone, it shows the input box wider than the rest of the other form objects. I prefer to have a % instead of fixed widths. Sampe screenshot images attached. Please bid/comment on the project and I will send you the URL to view on your iphone. ## Deliverables 1) All deliverables will be considered "work made for hire" under U.S. Copyright law.
