The design type that employs a single column layout with responsive headers and footers is best identified as responsive aware. This design approach is tailored specifically for optimal performance across various screen sizes and devices, ensuring that the content adapts effectively without compromising on usability or aesthetic appeal.

Responsive aware design incorporates fluid grids and flexible images that scale and rearrange content to fit the viewport, enhancing the user experience regardless of the device being used. The single column layout simplifies navigation and reading on smaller screens, while the responsive headers and footers ensure that essential information and navigation remains accessible.

Other design types may focus on different aspects, such as mobile aware, which could imply a design that is only minimally adjusted for mobile devices, or mobile friendly, which indicates compatibility but might not implement the full range of responsive design principles. Responsive, while suggesting adaptability, does not specifically denote the awareness around creating a recognizable single-column format that characterizes responsive aware layouts.
