Wordpress Customization

Need help to modify the Wordpress default theme 1.6. I need to make the page narrower because I need to imbed the Wordpress pages inside an iframe. I have already adjusted the main index page and reduced the width. I also adjusted the background images to match the new page width. I need help with all the other components, like other pages, header, footer, sidebar, etc.. Also, the color for the default theme is blue. I need to change the image in the header to a different color and reduce the header's height. Since the overall width of the page has been reduced, the content areas inside the pages need to be adjusted. I noticed that a lot of the layout is controlled via stylesheets. So CSS knowledge is necessary. Also, the template pages are in PHP. ## Deliverables All changes made to templates and stylesheets will have to be documented and commented clearly for future reference.
