How to make a block with the grid, bootstap 3?

Got an assignment to make a block:
The background divides the block in half, but the main content should be inside the main div.container. Made structure as at the link above, but placing two of these unit one above the other, the content of the bottom began to come to the top(at the transition from col-md-6 col-sm-12). Tell me what other possible solutions?
