Built into the site
- Semantic headings, landmarks, lists and source links.
- Keyboard-accessible navigation, search, filters and visible focus states.
- A skip link and clear current-page and expanded-state announcements.
- High-contrast text, non-color category labels and reduced-motion support.
- Responsive layouts that reflow without horizontal page scrolling.
- Descriptive alternative text for meaningful images; decorative graphics are hidden from assistive technology.
- Print styles for classroom learning guides.
Known limits
External sources are controlled by their publishers and may not meet the same accessibility standard. Some technical titles and product names are necessarily specialized; profile summaries aim to explain them in plain language.
Reporting a barrier
Record the page address, the barrier and—if useful—the browser or assistive technology involved. Inventorbook will publish a feedback address after the mailbox is verified and actively monitored.
