Advantages of separate stylesheets

There are lots of advantages of working this way, including:

  1. Reduced filesize - each CSS definition is written only once
  2. Reduced bandwidth - web browsers will remember (cache) the contents of CSS file, so don't need to download the file again with each new page that uses it
  3. Easier updating - you only have to change styles in one place for them to change site-wide
  4. Separates the work of styling and creating content - you can create all your HTML pages first, applying sensible semantic markup, class names and IDs, and then do all your design work later on your style sheets.
