Devllo Accessibility Controls

Devllo Accessibility Controls provides a lightweight, privacy-first accessibility widget that lets visitors adjust how they read and interact with your site. It focuses on user-controlled presentation (text size, contrast, reading preferences) and admin guidance (checks and hints). The plugin complements good accessible design—it does not replace design, development, or manual accessibility testing.

Key visitor controls:

• Text size (increase, decrease, reset)

• Line, letter, and word spacing

• Text align left

• Dyslexia-friendly font (OpenDyslexic, bundled)

• High contrast, grayscale, and dark modes

• Brightness control

• Reading mode (narrower column, focus state)

• Reading guide and reading mask

• Big cursor and link highlighting

• Focus outline enhancement, high visibility focus, and reduced motion

• Calm mode (reduces sidebars, sticky bars, and auto-rotating content)

• Larger click targets

• Hide images and reset preferences

• Preferences stored locally (localStorage) and restored on return visits

Admin features:

• Tabbed settings page with categorized, per-feature toggles (General, Visual, Text, Reading, Navigation, Widget, Statement)

• Widget customization (label, colors, size, position)

• Accessibility Guidance page: 25-item WCAG-inspired checklist grouped by principle (Perceivable, Operable, Understandable, Robust), with a live summary of reviewed / needs attention / not applicable items

• Automated, informational checks (skip link, headings, image alt sampling, etc.) with clear status indicators

• Block editor hints panel with contextual suggestions

• Frontend quick check via the admin bar

• Accessibility statement generator (creates a draft page)

What this plugin does NOT do:

• It does not perform a full accessibility audit or produce legally-binding compliance reports.

• It does not automatically fix content — it helps visitors and site owners identify and mitigate presentation issues.
