/* Sito di Piccoli Programmatori.
   Layout: fumetti (riquadri con contorno e ombra piena) su un tappetino a
   puntini, come i materiali stampati. Un solo font, Kanit: ExtraBold Italic
   per i titoli, dritto per i testi. Un solo tema chiaro, scelto apposta:
   testo scuro su fondi pastello, come sulla carta. */
