Responsive design in DITA map outputs is essential for ensuring that content adapts to different screen sizes and devices, providing an optimal reading and navigation experience for users on desktops, tablets, and mobile devices.

Key Considerations for Responsive Design

Responsive design is crucial when publishing DITA maps for digital consumption, as it ensures content displays and functions effectively on various devices. Key considerations include:

• Media Queries: Use media queries in the CSS stylesheets to define how content should be presented at different screen sizes. For example, certain elements can be stacked vertically on small screens but align horizontally on larger screens.
• Flexible Layouts: Design layouts that can expand or contract to fit different screen dimensions. For example, use flexible grids and relative units (e.g., percentages) for element sizing to accommodate varying screen widths.
• Optimized Navigation: Ensure that navigation elements, such as tables of contents and menus, adapt to the screen size. On smaller screens, consider using collapsible menus or slide-out navigation for a better user experience.

Example

A DITA map is being published as online documentation for a software application. In the CSS stylesheet, media queries can be used to address responsive design.

<style>
        /* For desktop screens */
        @media (min-width: 768px) {
            .topic {
                width: 70%;
                float: left;
            }
            .toc {
                display: block;
            }
        }

        /* For small screens (e.g., mobile) */
        @media (max-width: 767px) {
            .topic {
                width: 100%;
                float: none;
            }
            .toc {
                display: none;
            }
        }
    </style>

In this example, the CSS uses media queries to specify different styling rules for desktop and small screens. On larger screens, topics are displayed side by side, and the table of contents is visible. On small screens, topics take up the full width, and the table of contents is hidden to provide a more user-friendly experience on mobile devices. This ensures that the DITA content adapts to the screen size for improved readability and navigation.
