Add CSS to an already existing site.

cathuggeriowacity  wrote My site is recently redesigned, but without CSS.

That's a neat trick.   I'd be very interested to see how it was done.  What's the URL?

You would get a much better answer if you posted a link to this site, as well as providing a few more details regarding what it is you want to do.

Check with the person who created your redesigned site, it is possible that they used something like wordpress, so the css file would not be easily accessible.

If it was created using image slices or some other none recommended method, I would still suggest asking the person who created it. To help further we will require the link to the live page, and more information on what it is you are trying to do.
