Also gut ... dann werde ich mal hier mein Problem ganz kongret schildern.
Ich habe mir die Laughlin-Vorlage genommen und schonmal die Farben, Kopf- und Fußzeile angepasst.
Hier mal eine Beispielseite:
Titelseite (http://imgur.com/x9z5o)
Jetzt zu meinen Wünschen:
a) Der weiße Balken über der Sidebar soll weg
b) Die Fußzeile ragt ein kleines Stück über die Sidebar - soll bündig sein
c) Der Hintergrund meines Titels soll farbig sein, jedoch nur auf der Titelseite (die folgenden Frame-title sollen weiß hinterlegt sein)
d) Zwischen den dunkleren Balken der Kopf und Fußzeile soll ein Farbverlauf von oben nach unten passieren
So ... und nun mein outertheme und colortheme (müsste ja reichen, oder?)
Colortheme:
