How is "operable" defined in the context of web accessibility?

In the context of web accessibility, "operable" specifically refers to the need for input methods to be accessible and usable by all individuals, regardless of their abilities or disabilities. This means that users should be able to easily interact with web content through various means, whether they are using a mouse, keyboard, touchscreen, or assistive technologies.

For example, implementing keyboard navigation, providing clear focus indicators, and ensuring that all interactive elements can be accessed without requiring mouse actions are all ways to ensure that a website is operable for individuals with different needs. This facet emphasizes the importance of accessibility not just for visual content, but for the interactions that users have with the site.

The other options do not capture the essence of what "operable" means in web accessibility. Visually appealing content is more about aesthetics than functionality, while ensuring that all images have alt text pertains to the concept of "perceivable" information, and maintaining aesthetic consistency across platforms is related to design coherence rather than operational accessibility.
