   Fyra i rad – stil
   css/connectfour.css   (connectfourmenu.php och connectfour.php)

   Förut var texterna runt brädet vita (#ecf0f1) och kanterna vita och
   genomskinliga, så i det ljusa temat syntes de inte. Spelsidan låste
   också hela sidan (html, body { overflow:hidden }), så på mobilen gick
   det inte att scrolla. Nu följer allt temat, och brädet blir klassiskt
   blått i det ljusa temat.

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