You can embed font declarations in CSS (the @font-face declaration), specifying a path to a download. The browser will download the font and show it on web pages with the declaration.

Google offers an array of freely-available (open source, actually, I think, but I'm not 100% sure) fonts that are hosted on their servers that you can use.

To quote from the "introduction" dialog [0]: "Hundreds of free, open-source fonts optimized for the web".

Looking further, the "about" page [1] provides a bit more information: "All the Google web fonts are open source. That means that you are free to to use them in any way you want, independent of whether you're working on a private or commercial project."

I'm not sure what license they're using, though . . . I can't find anything but Google's standard "terms of service" license anywhere on the site.

The licenses are on the individual fonts' pages (try the "Pop Out" links.) Most of them are under the SIL Open Font License.

That makes a lot more sense... I'm a little behind the times I guess with my CSS.

The fonts are delivered from Google in real-time and don't have to be pre-downloaded. That's the beauty of it!

But of course Arial is still a good default.

Helvetica usually looks like shit on Windows if the user happens to have it. So you might try a different order, or just rely on most Mac users having Helvetica Neue.
