My goal is to replicate the layout shown in this screenshot view screenshot here
I want the layout to be responsive, with DIV B moving below DIV A when the screen is resized.
DIV B is positioned absolutely to cover content and DIV C.
Both DIV C and DIV A need to span the full width of the screen.
I've managed to achieve the desired layout on desktop, but I'm struggling to make it responsive. Any assistance would be greatly appreciated.
