Hi. My name is Sebastian. I'm Director Technology at Argonauten in Hamburg, give tech- classes at Miami Ad School and FH Wedel. I love to travel around the world, good food and building fancy stuff with (web-) technologies.

Wenn man einmal das linke Hauptmenü eingeklappt hat, dann wird es nach jedem Seiten-Reload erneut eingeklappt. Und bei diesem Verhalten bleibt es, das Menü bleibt weiter eingeklappt. Der Wert dafür wird nicht in einem Cookie gespeichert, sondern direkt in der […]
