Legible to everyone, or it does not run.

The accessibility standard we hold ourselves to is the same one we hold our advertisers to — and we reject creative that fails it.

How this site is built to WCAG 2.2 AA, what we have tested, the accessibility rules we impose on advertising creative, and how to tell us when we fall short.

Last updated 12 January 2026.

The standard

This site is built to meet WCAG 2.2 Level AA. We believe it does so throughout. Where we find a gap we fix it rather than logging an exception.

What that means here

  • Every page has one h1, a logical heading order and landmark regions.
  • A skip link precedes the header on every page.
  • Text meets 4.5:1 against its background, and large text and interface borders meet 3:1 — on the navy sections as well as the light ones.
  • Every interactive control is reachable and operable by keyboard, with a visible focus ring that is never removed.
  • The collapsed navigation traps focus while it is open and closes on Esc.
  • The horizontal case-study rail is a focusable region, so it can be scrolled without a pointer, and it becomes a vertical stack in a narrow container.
  • Charts are drawn in CSS and carry a text description; no information is conveyed by colour alone.
  • Images carry descriptive alternative text; decorative marks are hidden from assistive technology.
  • Form fields have persistent visible labels, errors are announced, and the first invalid field receives focus.
  • prefers-reduced-motion disables every count-up, reveal, parallax and transition on the site.
  • The layout reflows without horizontal scrolling from 280 px to 3840 px, and at 400% zoom.

Accessibility rules for advertising

Advertising creative is held to the same standard, and creative that fails it is rejected regardless of what has been paid:

  • Nothing may flash more than three times a second.
  • Animation must come to rest within fifteen seconds and may not loop more than three times.
  • Audio may not play without a deliberate action, and video must carry a visible pause control.
  • Every film carries captions, burned in and as a separate track.
  • Print type may not fall below 7 pt positive or 9 pt reversed.
  • Newsletter artwork must survive dark-mode inversion.

What we have tested

Keyboard-only navigation; VoiceOver on Safari; NVDA on Firefox; 400% browser zoom; Windows High Contrast; forced-colours mode; and rendering from 280 px to 3840 px. Contrast ratios were calculated for every text and surface pair used in the stylesheet rather than sampled.

Known limitations

  • The specifications tables are wide by nature. They scroll horizontally inside their own container rather than on the page, and the printed version reflows to the paper width.
  • Web fonts are served from a third party. If they fail to load, the page falls back to a system stack and remains fully readable.

Telling us

If any part of this site or of a Montlior advertisement is difficult to use, write to accessibility@montliorgroup.example. We reply within five working days, and we will tell you what we intend to do and when. If a fix will take longer than a fortnight, we will offer the content another way in the meantime.
