Accessibility statement for gaspwiki.com
403page labs is committed to making the GASP Standard usable by everyone. This statement applies to the website at gaspwiki.com, including the metric pages, definitions, guides, the relationship explorer, the TWIN World Modifier simulator, the dashboard examples and the metrics health check.
Conformance status
The site is designed to conform with the Web Content Accessibility Guidelines (WCAG) 2.1 at Level AA, the level referenced by the European harmonised standard EN 301 549 and by the European Accessibility Act. Where practical we also apply the additional Level AA criteria introduced in WCAG 2.2, such as minimum target size and focus appearance.
The site is partially conformant with WCAG 2.1 Level AA. Partially conformant means that some parts of the content do not yet fully conform. The known exceptions are listed below.
What we have done
- Every page renders its full content as HTML without requiring JavaScript, including all metric definitions, formulas and benchmarks.
- A skip link, consistent landmarks, a single top-level heading per page and a logical heading order on every page.
- Visible keyboard focus on every interactive element, and keyboard operation of menus, dialogs, tabs and the search modal, including Escape to close.
- Text colours meet a minimum contrast of 4.5:1 against their backgrounds in both the light and dark themes. Links inside running text are underlined, not identified by colour alone.
- Reduced-motion preferences are respected. Decorative animation is disabled when the operating system requests it.
- Layout adapts from small phones to large displays and supports 200 percent browser zoom without loss of content.
- Charts and diagrams carry accessible names, and the underlying data is always available as text on the same page or on the linked metric pages.
Known limitations
The following content is not fully accessible. We are working to address each item.
- Relationship explorer and TWIN World Modifier. These are interactive force-directed graphs. Nodes can be focused and activated from the keyboard, but the spatial layout itself is not conveyed to screen reader users. The same relationships are listed as text on every individual metric page under Related Metrics.
- Dashboard example charts. Sparklines, gauges and heat maps in the dashboard examples are illustrative. Each carries a text summary, but individual data points are not exposed to assistive technology.
- Code and formula blocks. Long formulas scroll horizontally on narrow screens rather than wrapping, which can require two-dimensional scrolling at high zoom levels.
Feedback and contact
If you find something on this site that you cannot access, or you need content in a different format, please tell us. Open an issue on the GASP Standard GitHub repository describing the page and the problem, or contact 403page labs directly. We aim to respond within ten working days.
Technical information
The site is built with Astro and React and is served as static HTML. Accessibility relies on HTML, CSS, JavaScript, WAI-ARIA and SVG. Content of the standard is also published as plain text at /llms.txt and /llms-full.txt and as JSON at /api/standard.json for use with any assistive or automated tool.
Preparation of this statement
This statement was prepared on 2026-09-06 and last reviewed on 2026-09-06. It is based on a self-assessment supported by automated testing with axe-core through Lighthouse across representative pages, a manual keyboard review of the navigation, search and interactive components, and a colour contrast audit of the design tokens. Testing with screen readers by users of assistive technology has not yet been carried out and is planned.
