How to apply CSS locally on any online page?

Question

For testing

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

Can I just apply the CSS locally to any online page?

It would be easier to edit and see changes locally until the CSS work is done.

I want to see the applied effect on Firefox and Internet Explorer.

Is this at all possible?

I think this is the closet way

but only for firefox

I found another better way

In FireFox, from the Web Developer toolbar, select CSS -> Add User Style Sheet, browse to wherever you stored it and click the Open button. When you are finished, just un-check the "Add User Style Sheet" on the toolbar CSS menu.

In Microsoft Internet Explorer, select Tools -> Internet Options... -> Accessibility... and check the "Format documents using my style sheets" box. Using the Browse button, open the lowvis.css style sheet from wherever you stored it, and click OK to both the Accessibility and the Internet Options panels. When you are finished, simply un-check the "...my style sheets" box on the Accessibility panel.
