Question: Creating a form that can be completed and submitted using the keyboard only adheres to which WCAG principle?
- Robustness
- Perceivability
- Understandability
- Operability
Explanation
This aligns with Operable because the requirement is about whether interactive elements can be used through keyboard navigation rather than a mouse. HubSpot’s accessibility guidance explicitly states that some visitors navigate webpages and forms with a keyboard or an assistive device that emulates one. A keyboard-only form flow depends on users being able to move focus through fields, reach controls, and trigger submission successfully. In HubSpot CMS work, that is an interaction requirement for form usability, not a visual or content-only requirement. HubSpot Developers+2HubSpot Developers+2
Why the other options are incorrect
A) Robustness relates to content being interpreted reliably by browsers and assistive technologies, not to operating form controls through the keyboard. HubSpot Developers+1
B) Perceivability relates to whether content can be detected through sight or hearing, such as labels and text alternatives, not to moving through and submitting a form with keyboard input. HubSpot Developers+1
C) Understandability relates to clarity and predictability of content and behavior, not to the ability to activate and submit controls without a mouse. HubSpot Developers+1
