CSS Modifications Needed

Hello, we require a css designer to modify the css code for a php script we recently purchased. Currently a section of the design does not align correctly when viewed using Mozilla FireFox. You will be required to modify the css stylesheet and any other applicable files in order to make the design work correctly with all browsers. We will send the winning bidder the nessesary files needed in order to make the changes. This project should be very easy for the right person who has experience with css code. If you require any additional information, please do not hesitate to let me know. ***Important...Payment for this project will be made only on full completion of the work. The design must fit correctly in all browsers. Payments will be made via the GetAFreeLancer Escrow at the completion of the project. PLEASE DO NOT BID IF YOU ARE NOT EXPERIENCED WITH CSS.
