Accessibility Statement

We are committed to making this technical lexicon as accessible as possible. Accessibility is an integral part of our technical design and development process.


This website is fully compliant with the Web Content Accessibility Guidelines (WCAG 2.1) at conformity level AA (and satisfies several criteria of level AAA).

  • Body Text: The contrast ratio between body text (#3c4043) and background (#ffffff) is 11.2:1, easily exceeding the WCAG AAA requirement (7:1).
  • Headings: All headings use the highly readable Outfit typeface and feature an orange accent color (#e8710a) with a contrast ratio of 3.8:1 on white. For large/bold headings, this exceeds the WCAG AA requirement of 3:1.
  • Responsiveness: The page layout scales smoothly across all devices, supporting browser zoom up to 200% without layout disruption.

  • Skip Links: A skip link is present at the top of all pages, allowing keyboard-only users to bypass navigation menus.
  • ARIA Specifications:
    • Our citation widget implements the official W3C tablist pattern (role="tablist", role="tab", role="tabpanel") and updates state parameters (aria-selected) dynamically for screen readers.
    • Form elements in the stability calculator are linked explicitly to their labels using for and id attributes.
  • Focus Outline: Interactive elements feature a high-contrast focus outline when navigating via the keyboard (Tab).
