Accessibility statement
Our commitment
The LATTICE Consortium wants this website to be usable by everyone, including people who browse with a screen reader, navigate by keyboard alone, need larger text, or rely on high-contrast settings.
lattice-project.eu is the website of a Horizon Europe research project. It is
not the website of a public-sector body, so Directive (EU) 2016/2102 does not
apply to it as a matter of law. We have chosen to follow that directive's
approach anyway, and we take WCAG 2.1 Level AA — the technical standard
behind the European harmonised standard EN 301 549 — as our target.
Conformance status
This website is partially conformant with WCAG 2.1 Level AA.
"Partially conformant" is the honest description. Every success criterion we were able to test is met, on every page, in both the light and dark themes. But we have not yet tested the site with assistive technologies or with disabled users, and a full conformance claim would not be credible without that. The gap is in our testing, not in any defect we currently know about.
How we tested
Date of test: 30 August 2026. This statement was prepared on the same day by the LATTICE Consortium and is based on that test.
Method: self-assessment. We measured the site's rendered pages directly in a browser, rather than relying on a summary score.
All twelve pages were checked in both themes, along with the page shown for an unrecognised address:
- Contrast of every visible text element, measured against the background actually composited behind it, including semi-transparent text.
- Heading structure, landmark regions, page titles, and the document language.
- Alternative text on images, and accessible names for links and buttons.
- Keyboard navigation, the skip link, and the visibility of the focus indicator.
- Reflow at a 320 pixel viewport width.
What we found and fixed on that date: text that failed the contrast threshold in one theme or the other — in the worst case a pale blue figure on the light background measuring 1.31:1 against a required 3:1 — and headings that jumped from level 1 or 3 straight to level 6, because a heading element was being used to style labels that are not document sections. Both are fixed across the whole site.
What we measured after the fixes:
| Criterion | Result |
|---|---|
| 1.1.1 Non-text content | Every image carries alternative text |
| 1.3.1 Info and relationships | One h1 per page, no skipped heading levels |
| 1.4.3 Contrast (minimum) | All text meets 4.5:1, or 3:1 where large |
| 1.4.10 Reflow | No horizontal scrolling at 320 px |
| 1.4.11 Non-text contrast | Focus indicator at 3.71:1 light, 4.06:1 dark |
| 2.4.1 Bypass blocks | Skip link to the main landmark on every page |
| 2.4.2 Page titled | Every page has a unique, descriptive title |
| 2.4.4 Link purpose | Every link has an accessible name |
| 2.4.7 Focus visible | 2 px outline on keyboard focus |
| 3.1.1 Language of page | Declared as English |
| 4.1.1 Parsing | No duplicate element identifiers |
| 4.1.2 Name, role, value | Every control has an accessible name |
Known limitations
We list these openly because they are the reason our conformance claim is partial rather than full.
- No assistive-technology testing. The site has not been tested with NVDA, JAWS, VoiceOver, or any other screen reader. Automated measurement cannot tell us whether the reading order makes sense, whether our labels are understandable when heard rather than seen, or whether any control is confusing in use.
- No testing with disabled users. Nobody who depends on assistive technology has yet been asked to try the site and tell us what does not work.
- No independent audit. The assessment above is our own.
- The theme choice is not remembered between visits. The site follows your operating system's light/dark setting, including live if you change it while reading. The control in the footer overrides it for the current visit only — nothing is stored, so the override resets on reload (the cookie policy explains why).
Nothing on this site is currently excluded as a disproportionate burden.
Not applicable
These parts of WCAG have nothing to apply to on this site as it stands today:
- Time-based media (captions, audio description). There is no video or audio on the site.
- Forms. There are no forms, and no fields that collect input. Contact is by email.
If we later publish video, deliverable PDFs, or a form, this statement will be updated before that content goes live.
Tell us about a problem
If something on this site is difficult or impossible for you to use, we want to hear about it — including for anything not covered by WCAG.
Email: accessibility@lattice-project.eu
We aim to acknowledge your message within 5 working days and to tell you what we intend to do, and by when, within 10 working days. If a fix will take longer, we will say so and offer the information you were trying to reach in another format.
It helps us if you can include:
- The address of the page.
- What you were trying to do, and what happened instead.
- The browser, operating system, and any assistive technology you were using.
You do not need to know why something is broken, or use any particular terminology, to report it.
If we do not respond
Because this is not a public-sector website, the national enforcement procedure established under Directive (EU) 2016/2102 does not cover it, and no supervisory body has jurisdiction over its accessibility.
If you are not satisfied with our response, please write to the project
coordinator, the Luxembourg Institute of Science and Technology, at
contact@lattice-project.eu, marking your message for the attention of the
project coordinator. We will treat a complaint about accessibility as we would
any other complaint about the conduct of the project.
Review
Statement prepared: 30 August 2026. Based on a self-assessment carried out: 30 August 2026. Next scheduled review: 30 August 2027.
We also review this statement whenever the site changes substantially, and whenever someone reports a problem that turns out to be real.
