Having issues with this website/survey not resizing well on iPhone or mobile devices.. [login to view URL] I require a freelancer to write the extra CSS i need to change this survey to make it size down well to smaller screen sizes.(particularly iphone and blackberry) THe output will be purely the CSS classes i need to append to and the values needed. (in the backend of this survey tool, it allows me to append CSS to the stylesheet) Thanks.. IMPORTANT Bidders, please address my issue in your bid, show to me that you understand what the problem is and that you can fix it for me. Please include the answer to this in your bids 4+5 = ??
