How do I do it? Where can I look up available custom fonts without subscribing anywhere. I don't want to use typekit or whatever you call it. I paid $30 to play with fonts, but I can hardly know what to do.
Here's an example that will change the font for the tagline on the Twenty Eleven theme using a font stack:
font-family: Georgia, Times, “Times New Roman”, serif !important;
You can read more about font stacks at http://unitinteractive.com/blog/2008/06/26/better-css-font-stacks/
Here's an example using the "FF Market" font which you setup on your Appearance → Custom Design → Fonts page:
font-family: ff-market-web-1,ff-market-web-2,"Helvetica Neue",Helvetica,Arial,sans-serif !important;
Note that for the 2nd option, you must use a font that is selected as one of the main options on the Appearance → Custom Design → Fonts page.
