   Minta – LAPOZHATÓ, új dizájn
   Modern, grafikus stílus: papírfehér + szén + egyetlen magabiztos indigó
   kiegészítő szín, kör-motívumokkal. Valódi 3D lapozás-animáció,
   javított technikával (statikus z-index, vendor-prefixelt backface
   -visibility, kevesebb réteg a lapon) a korábbi "snatchy" hatás ellen.
