Creating a form that can be completed and submitted using the keyboard only adheres to which WCAG principle?

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
