Glossary by Progress Planner is a modern, accessible WordPress glossary plugin that automatically transforms glossary terms in your content into interactive elements with click-triggered popover definitions.<\/p>\n
Key Features <\/h4>\n\n- Custom Post Type<\/strong>: Register glossary entries with custom fields (no content editor needed)<\/li>\n

- Case Sensitive Matching<\/strong>: Optionally match terms only when case matches exactly<\/li>\n
- Disable Auto-Linking<\/strong>: Allow entries to appear in the glossary without being automatically linked in content<\/li>\n
- Semantic HTML<\/strong>: Uses
<dfn><\/code> and <aside><\/code> elements with proper ARIA attributes<\/li>\n- Schema.org Integration<\/strong>: Full DefinedTerm and DefinedTermSet structured data support
\n- Integrates with Yoast SEO schema graph when available<\/li>\n

- No External Dependencies<\/strong>: Pure WordPress core functionality, no third-party plugins required<\/li>\n<\/ul>\n
How It Works <\/h4>\n
Once you've added glossary entries, the plugin automatically:<\/p>\n
\n- Scans post and page content for mentions of glossary terms (case-insensitive by default, or case-sensitive if enabled)<\/li>\n
- Transforms the first mention<\/strong> of each term into an interactive element (unless auto-linking is disabled for that entry)<\/li>\n
- Shows a popover with the short description when users click on the term<\/li>\n
- Adds a \"Read more\" link to the full glossary entry<\/li>\n<\/ul>\n
Browser Support <\/h4>\n
The plugin uses modern web platform features:<\/p>\n
Popover API:<\/strong><\/p>\n\n- Chrome\/Edge 114+<\/li>\n
- Safari 17+<\/li>\n
- Firefox (experimental support behind flag)<\/li>\n<\/ul>\n
CSS Anchor Positioning:<\/strong><\/p>\n\n- Chrome\/Edge 125+\/Safari: supported<\/li>\n
- Firefox (not yet supported)<\/li>\n<\/ul>\n
For older browsers, consider adding the Popover API polyfill. CSS Anchor Positioning gracefully degrades (popovers may not position optimally but will still be functional).<\/p>\n
Accessibility <\/h4>\n
The plugin follows WCAG 2.1 Level AA guidelines:<\/p>\n
\n- Semantic HTML elements (
<dfn><\/code>, <aside><\/code>, proper roles)<\/li>\n- Full keyboard navigation with visible focus indicators<\/li>\n
- ARIA attributes for screen readers<\/li>\n
- Click-to-open behavior (not hover) for better accessibility<\/li>\n
- Auto-dismissing popovers that don't overlap<\/li>\n
- Color contrast ratios meet AA standards<\/li>\n<\/ul>\n
Schema.org Structured Data <\/h4>\n
The plugin automatically adds Schema.org structured data for glossary entries:<\/p>\n
\n- With Yoast SEO<\/strong>: Integrates with the Yoast schema graph API to add DefinedTermSet and DefinedTerm entries in JSON-LD format<\/li>\n
- Without Yoast SEO<\/strong>: Outputs Microdata markup directly in the HTML using
itemscope<\/code> and itemtype<\/code> attributes<\/li>\n<\/ul>\nEach glossary entry includes:<\/p>\n
\n- @type: DefinedTerm<\/li>\n
- name: The term title<\/li>\n
- description: Short description (shown in popovers)<\/li>\n
- url: Anchor link to the entry on the glossary page<\/li>\n
- alternateName: Array of synonyms (alternative terms)<\/li>\n<\/ul>","screenshots":"
