/* =====================================================================
   Tre i rad – stil
   css/tictactoe.css   (tictactoemenu.php och tictactoe.php)

   Förut var texterna runt brädet vita (#ecf0f1) och kanterna vita och
   genomskinliga, så i det ljusa temat syntes de inte, och spelsidan
   låste all scroll (html, body { overflow:hidden }). Nu följer allt
   temat, och brädet blir ljust i det ljusa temat.

   style.css färgar "main button" i ljust tema och hav – reglerna här
   har id i väljaren och vinner därför.
