Which of the following best describes 'robust' in the context of web accessibility?

In the context of web accessibility, 'robust' refers to the need for web content to function well across a variety of platforms and devices, ensuring a consistent experience for all users, including those with disabilities. This means that the content should be developed with standard web technologies and practices so that it remains accessible on different browsers, assistive technologies, and devices such as mobile phones, tablets, and desktops. The emphasis on robustness aims to ensure that as technologies evolve, the accessibility of content remains intact.

This concept is crucial because it addresses the reality that users will interact with web content using an array of tools and devices. By ensuring that the content is robust, web developers can help facilitate a more inclusive environment, allowing all users to access information seamlessly, regardless of their method of interaction.
