Accessibility Widget Barrierefreiheitsstärkungsgesetz (BFSG)

The Accessibility Widget adds a customizable toolbar to your Drupal site, helping visitors with disabilities access your content. It provides text resizing, contrast modes, screen reader, and voice navigation - ensuring compliance with BFSG, ADA, and WCAG 2.1 standards.

Features

The Accessibility Widget provides comprehensive accessibility tools through a single button (♿) that appears on your site:

Visual Adjustments:

• Font size scaling (50% - 200%)
• Multiple contrast modes (Dark, Light, High Contrast, Monochrome)
• Color adjustments for text, titles, and backgrounds
• Highlight links and titles for better visibility
• Dyslexia-friendly font option

Reading & Navigation Tools:

• Built-in screen reader with text-to-speech
• Voice navigation commands (German & English)
• Reading guide/ruler for line tracking
• Adjustable letter spacing and line height
• Large cursor option
• Animation pause control

When to use this module:

• Your site needs to comply with accessibility laws (BFSG becomes mandatory June 28, 2025)
• You want to improve user experience for visitors with disabilities
• You need a quick accessibility solution without major code changes
• Your organization requires ADA, Section 508, or WCAG compliance

Post-Installation

Once installed and enabled, the widget works automatically:

1. No configuration needed! A blue wheelchair icon (♿) appears in the bottom-left corner of all public pages
2. Automatic exclusion from admin pages to avoid interference
3. User preferences are saved locally in the browser (GDPR compliant)

Optional customization:
To exclude the widget from specific pages, add this to your theme's .theme file:

function YOURTHEME_page_attachments_alter(array &$attachments) {
  if (\Drupal::service('path.matcher')->isFrontPage()) {
    unset($attachments['#attached']['library']['accessibility_widget/accessibility-widget']);
  }
}

Similar projects

Several accessibility modules exist, but the Accessibility Widget is unique because it:

• Requires zero configuration - Works immediately after installation
• Includes voice navigation - Supports voice commands in German and English
• Provides built-in screen reader - No need for users to have their own
• Focuses on BFSG compliance - Specifically designed for the 2025 German law
• Respects privacy - No external services or data collection

Compare with:

• Accessibility - Focuses on content accessibility checking, not user tools

• Text Resize - Limited to font sizing only
