Keyboard Section Widget Builder

How to use Keyboard Section Widget Builder

Build a real small interactive section prototype rather than adding disconnected ARIA attributes to static markup. Related tabs and accordion profiles share one export workflow, with original text, distinct control/panel identities and a closed keyboard state model. The downloadable page binds its own trusted script and style bytes to SHA-256 policies; the tool site displays source text and never mounts your generated widget.

1. Enter two to ten original plain-text sections and a single-line title; choose a distinct ASCII ID prefix.
2. Choose automatic/manual horizontal tabs or single/multiple-open accordions, then build the complete artifact.
3. Download and open the generated page, test its real keyboard and assistive-technology behavior, and review integration requirements before reusing it.

Good to know

• At most 30,000 JSON characters, two to ten sections, a 160-character title, 80-character headings and 2,000 characters per body. Titles/headings are single-line. Body CRLF/bare CR normalize to LF. Unknown keys, duplicate JSON members, malformed Unicode and controls other than tab/CR/LF are refused. No user HTML, CSS, URLs or JavaScript is accepted as active content.
• The ID prefix starts with an ASCII letter and contains at most 40 ASCII letters, digits, underscores or hyphens. All control/panel/label IDs derive from it and source order; identical visible labels do not collapse. Use a distinct prefix when reusing multiple exported components in another document.
• Tabs are horizontal with first panel initially active. Arrow Left/Right wraps, Home/End moves to endpoints, and manual tabs activate through native Enter/Space or click. A focus departure resets the tab-list entry point to the active tab. Up/Down, modifiers, Tab/Shift+Tab and Escape are not intercepted. No popup menus, deletion or dynamic network panels are supported.
• Accordions start with the first section open. Single mode allows at most one open and permits all closed; multiple mode permits several. Native buttons handle Enter/Space; optional Up/Down/Home/End navigation only changes header focus. No region role is added to every panel, avoiding a proliferation of landmarks.
• The original standalone artifact initially exposes every text section with disabled controls, then installs only fixed trusted behavior. Script/style hashes are calculated from the exact generated bytes. Web Crypto SHA-256 is required. No app CSP change, sandbox embedding, user-source mounting, code evaluator, storage, permissions, external request, animation, timer or shared engine adapter is involved.
• The generated code is a bounded prototype of selected APG interactions, not a full WCAG/APG conformance or browser/screen-reader certification. Real pointer/keyboard focus, CSP, mobile layout, no-script fallback, copied-code integration and assistive technology must be checked in their actual environment. Output is a complete HTML page, not a promise that pasting it into an arbitrary framework will work.
• Processing is local. Output is limited to 1,000,000 text characters unless a stricter file limit is stated.
