   Tangentbordet – stil
   css/keyboard.css   (keyboardmenu.php och keyboard.php)

   Förut var rubriker, nivånamn, tecknet att skriva och tangenterna vita
   (rgba(255,255,255,…)), så i det ljusa temat syntes bara fingerbanden.
   Nu följer allt temat. style.css färgar "main button" i ljust tema och
   hav – reglerna här har id i väljaren och vinner därför.
