Update 2007-06-02 00:05: Installed wp-syntax and it looks good. I now need to fix my CSS to use monospace, my first attempts didn’t seem to result in the correct display.
Update 2007-06-02 00:12: So my CSS is working, it was just that Firefox decided on some weird monospace font, which wasn’t monospaced at all.
