/* The proper way for web browser environment independent font handling in html/css is,
 * to defining a font search path ending in serif, sans-serif, or monospace, e.g.:
 * <style>body {font-family: Verdana,Arial,Helvetica,sans-serif;}</style>

 * For more satisfying results on html files without proper font search path,
 * popular fonts which are candidates for further font aliases similar to
