What is defined as 'keyboard accessibility'?

Keyboard accessibility refers to the ability of users to navigate and interact with a website using a keyboard instead of a mouse. This is particularly important for individuals with physical disabilities or motor impairments who may find it challenging or impossible to use a mouse.

The correct choice highlights that all interactive elements on a webpage must be operable via keyboard controls. This means that elements such as links, buttons, and forms should be reachable and usable through various keyboard actions like tabbing and pressing the Enter key. Ensuring keyboard accessibility is a fundamental aspect of web design that makes online content more inclusive, allowing a broader range of users to effectively interact with the web.

Other options touch on different aspects of accessibility but do not specifically address the core concept of keyboard accessibility. For example, using voice commands is a different accessibility method that caters to a distinct user need, and while keyboard shortcuts can enhance usability, they are not a requirement for keyboard accessibility per se. Similarly, ensuring text is readable relates more to visual accessibility rather than the ability to navigate a site using keyboard controls.
