CSS - Font for a web based editor

Question

I'm building a web based code editor. I'm currently using

font-family : "Courier New", Courier, monospace 

as the rule for both line numbers and the source code.

• Does it work on every OS?
• Is there a better font than Courier new that's both targeted towards source code and installed in majority of computers?

Answer 1

Taken from Stack Overflow's CSS:

code {     font-family: Consolas, Menlo, Monaco, Lucida Console, Liberation Mono, DejaVu Sans Mono, Bitstream Vera Sans Mono, Courier New, monospace, serif; } 

You can be sure it's been tested :)
