CSS: Fallback fonts

you can specify multiple fonts:

p {
    font-family: "Times New Roman", Times, serif;
}

The browser will try the first one, if that one isn’t available the second, and so forth. In the end it uses the family serif, so the browser chooses any serif font. You should use the monospace family.

So in your case, something like this is what you want:

p {
    font-family: "Lucida Console", "Courier New", monospace;
}
