Install

No release zip yet. The repository archive installs, but the folder name will carry the branch suffix and updates will not flow:

wp plugin install https://github.com/zeulus/wp-accessibilitor/archive/refs/heads/main.zip
Readme github.com/zeulus/wp-accessibilitor ↗

Accessibility toolbar for WordPress (Polish name: Dostępnik). A small floating button opens a panel of display adjustments:

  • Larger / smaller text (three steps; scales the whole page except the toolbar)
  • Grayscale
  • High contrast — black background, white text, yellow links (21:1)
  • Negative — inverted colours, photos and videos shown normally
  • Light background — white background, black text, dark blue links
  • Underline links
  • Readable font
  • Reset

Below the buttons you can show up to four links — e.g. your accessibility statement, accessibility report and action plan, which public bodies in many countries are required to publish.

The plugin also improves embedded videos: iframes without a title get one (WCAG 4.1.2), YouTube embeds are switched to youtube-nocookie.com and lazy-loaded.

Everything runs in the visitor's browser. No external services, no cookies, no tracking. Preferences are kept in localStorage only.

Built for keyboard and screen-reader users: aria-expanded, aria-pressed, a labelled region, Escape closes the panel, visible focus.

Installation

  1. Copy the accessibilitor folder (or this repository) to wp-content/plugins/ and activate the plugin.
  2. Go to Settings → Accessibility, choose the buttons you want and add your links.

Requires WordPress 6.4+ and PHP 8.0+.

For theme authors

Text-size modes use CSS zoom on the direct children of <body> (except the toolbar). The header's inline size shrinks in CSS pixels, so a menu built with a container query (container-type: inline-size on the menu wrapper) switches to its mobile layout instead of overflowing. Media queries alone do not react to zoom.

Modes are classes on <html>: accessibilitor-fs-1..3, accessibilitor-grayscale, accessibilitor-contrast, accessibilitor-negative, accessibilitor-light, accessibilitor-underline, accessibilitor-font.

Development

  • Coding standard: WordPress Coding Standards (phpcs --standard=WordPress).
