/* If the image is inside container, the blue bar should probably be full width.
   The wrapper has padding, so the image is not full bleed.
   But the blue bar is full bleed.
   Let's check the design again. The design likely has the image full width of the container, or full viewport width?
   The reference shows the image aligning with text?
   Let's assume container width for image.
   The blue bar is definitely full width background.
