How to apply css locally on any online page?
For testing 

I don't want to upload css to FTP on each change till site complete , but site and content is online. (i'm not talking about saving page locally then apply css)

Can i just apply css locally to any online page.

it would be easier to edit and see changes locally till css work end.

and i want to see applied effect on FF and IE.

How to do that? Is it possible.
