If all of your pages are written by hand and each has its own complete html then you would have to update all pages to include the css file, however if all of the pages share a common header then you only need to include the css in the header file. I could be much more helpful if I knew some details about the page (what it's written in etc) because there are so many different ways websites are being made with different consequences. You can write me privately if you don't want your site details to become public.
