What does making web content 'Robust' entail?

Making web content 'Robust' entails adhering to standards for compatibility. This principle is crucial because it ensures that content remains accessible and usable across a wide variety of browsers, devices, and assistive technologies. By following established web standards, developers increase the likelihood that their content will be understood and rendered correctly by diverse platforms and tools, which is essential for users with disabilities who may rely on specific technologies to access digital content.

Robust content enables ongoing accessibility not just for current technologies but also for future advancements, as adherence to standards typically anticipates and accommodates various user needs. This principle is a key aspect of the Web Content Accessibility Guidelines (WCAG), which emphasize the importance of ensuring content is compatible with user agents, including those that might be developed after the initial content creation.
