What does the principle of "Robust" imply in web accessibility?

The principle of "Robust" in web accessibility emphasizes that content must be compatible with current and future user agents, including browsers, assistive technologies, and various devices. This principle is crucial because it ensures that as technology evolves, the accessibility of the content remains intact. By adhering to this principle, developers can create web content that is adaptable and reliable across different platforms, thereby promoting inclusivity for all users, regardless of their method of accessing information.

This approach encourages the use of standardized coding practices, which help ensure that new devices and assistive technologies can interpret the content correctly. As a result, the content remains actionable and usable for individuals with diverse needs over time. The "Robust" principle is vital in maintaining long-term accessibility, even as user requirements and technologies change.
