Creating CSS for navigation & top page sections

For the website [login to view URL] all the pages will have the same top section and left side section. I want to create two style sheets that let me change these sections in all the pages at once at some point in the future. The first of the two style sheets will incorporate the area where the two logos are at the top of the page. This should let me incorporate other aspects into this area such as an enter your email to receive a newsletter in this section at some point in the future. The second of the two style sheets will incorporate the area of the left hand side of the page from 'Find a Flight' to the bottom of the 'Travel Insurance' picture. I want this to let me to add one or two more similar graphic links to all the pages in this secion via this style sheet at some point in the future. ## Deliverables 1) Complete and fully-functional style sheets in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
