Styling in DITA publishing is a critical component that determines the visual presentation of content in both print and digital output formats. It defines the fonts, colors, layouts, and overall aesthetics to ensure content is not only well-structured but also visually appealing and user-friendly.

DITA styling involves visual consistency, user experience, responsive design, and accessibility.

• Visual Consistency: Styling in DITA publishing helps maintain visual consistency across various output formats. Whether it’s print documents, web pages, or mobile apps, consistent styling ensures that users recognize and associate the content with the organization’s brand.
• User Experience: Styling significantly impacts the user experience. It involves choosing appropriate fonts, colors, and spacing to make the content easy to read and navigate. Proper styling enhances user engagement and comprehension.
• Responsive Design: For digital outputs, styling also includes responsive design considerations. This means ensuring that content adapts to different screen sizes and devices. Proper styling ensures content remains readable and visually appealing on various platforms, from desktop monitors to mobile phones.
• Accessibility: Styling should consider accessibility standards (such as WCAG) to make content usable for people with disabilities. This may involve ensuring sufficient color contrast for text, providing text alternatives for images, and structuring content for screen readers.

Example:

A software company uses DITA to create user guides for its product. Styling plays a crucial role in their DITA publishing:

Print Manual: When generating a print manual, the styling defines the use of a specific corporate font, sets margins and page layouts, and ensures that headings are consistent in size and color. This makes the manual visually cohesive and branded with the company’s identity.

Online Help: For their online help system, styling adjusts fonts and text sizes to improve readability on different screen sizes. It also ensures that hyperlinks are visually distinct, making them easy to identify and click. The styling complies with accessibility standards, including providing alt text for images.

Mobile App: The same content is repurposed for a mobile app. In this case, styling optimizes the content for smaller screens. It might use a different font size and layout for the app, ensuring that users have a great reading experience on mobile devices.
