OK so i would do this:
1. Add a Container Block. Remove the Padding ( ie. set to 0 ), add a Background Image and then select the Dynamic Background.
2. Inside that Container add another Container which you can add your white background, and give it some top margin eg 40% to create the height of the featured background and to position the White box to the bottom.
3. Fill the white container with your blocks for the title and the meta.
