D2i Accessibility Toolkit

Description

D2i Accessibility Toolkit injects a floating accessibility panel into the front-end of any WordPress site. Visitors can activate assistive adjustments in a single click without needing to change their browser or operating system settings.

Important notice: This plugin helps users customise their browsing experience. It does not automatically make your website fully compliant with WCAG, ADA, Section 508, or EN 301 549. Website owners remain responsible for ensuring their content (semantic HTML, image alt text, captions, heading structure, and color contrast in their own designs) meets applicable standards.

Features

• Contrast modes — Dark, Light, High Contrast (cycle through)
• Highlight Links — high-visibility outlines and backgrounds on all links
• Bigger Text — 100 % → 120 % → 140 % → 160 % → 180 % → 200 % (rem-based, reflows correctly)
• Text Spacing — applies WCAG 1.4.12 exact values (line-height 1.5, letter-spacing 0.12 em, word-spacing 0.16 em, paragraph spacing 2 em)
• Pause Animations — stops CSS animations/transitions; pauses <video autoplay>; respects prefers-reduced-motion automatically
• Hide Images — hides img/picture/SVG; injects alt text as visible text nodes
• Dyslexia Friendly — applies OpenDyslexic font (bundled locally, no CDN), increases line-height and letter-spacing
• Big Cursor — 64 px white or black cursor SVG, locally bundled
• Line Height — Default → 1.5 → 1.75 → 2.0 → 2.5
