Is it possible to link to an external CSS layout and have it so I only have to type in the stuff for the content section on whatever page I am linking from. Sort of like SSI but with CSS. Like have all of my links and header sho up an all my pages and ba able to change the content section for different pages from their respective coding. :confused::confused::confused::confused:

You can use css for styling all content like this: http://www.lissaexplains.com/css2.shtml#external
but you cannot use it for including content itself.
For that you need ssi, php or javascript.
