Website accessibility

How the OsteoplusX site works for people with reduced vision or motor skills: text size, contrast, keyboard use, animation off. How to report a problem.

Version of

Who the site is for

We build this site first of all for people over 55. Many read on a phone in the evening, when their eyes are tired. Some have reduced vision, trembling hands or painful finger joints. The site should be comfortable for them and work without a mouse and with screen readers.

Standards

We aim to meet WCAG 2.2 at level AA[1]1Web Content Accessibility Guidelines (WCAG) 2.2 — W3C, 2023To the list of sources →. It is an international set of testable requirements for text, contrast, navigation and forms.

In Russia, the national standard GOST R 52872-2019 covers website accessibility for people with disabilities[2]2ГОСТ Р 52872-2019 Интернет-ресурсы и другая информация, представленная в электронно-цифровой форме. Требования доступности для людей с инвалидностью и других лиц с ограничениями жизнедеятельности — Росстандарт, 2019To the list of sources →. It is based on WCAG 2.1, and we use it as a reference. The site has not yet had a formal GOST conformance assessment.

We also follow the W3C guidance on older users[3]3Developing Websites for Older People: How WCAG 2.0 Applies — W3C WAI, 2018To the list of sources →.

What is already in place

These requirements are built into the site, and we check them before every release. There has been no external audit yet; see Known limitations below.

Reading settings (Aa)

The Aa button in the header opens the reading settings. You can set the text size to 100, 118 or 135 %. The Animation switch in the same panel turns motion off across the site. The same settings are repeated in the footer of every page. Your choice is stored only in your browser, and the Forget my choices button clears it.

Text and readability

  • Body text is 18–20 pixels with a line height of 1.6.
  • Lines are no longer than 70 characters, so the eye finds the next line easily.
  • Text is not justified, so there are no large gaps between words.
  • Pages reflow at 200 % zoom and on screens from 320 pixels wide.
  • Sentences are short, and terms are explained the first time they appear.

Contrast and colour

  • Body text contrast is at least 7:1 where possible and at least 4.5:1 everywhere.
  • The background is slightly muted, which reduces glare.
  • Colour is never the only signal: links are underlined and states have text labels.

Keyboard and focus

  • The whole site works without a mouse, using Tab, the arrow keys and Enter.
  • The focused element has a visible 2-pixel outline. We never hide it.
  • Every page starts with a Skip to content link that jumps past the menu.
  • The sticky header never covers the element you moved to with the keyboard.
  • Buttons and links are at least 24 × 24 pixels; main buttons are at least 44 × 44.

Animation and motion

  • If Reduce motion is on in your device settings, the site turns animation off automatically.
  • Nothing flashes or moves on its own, and there are no carousels.

Diagrams and structure

  • Every diagram has a caption and a text description for screen readers.
  • Everything important in diagrams and interactive blocks is also in the text. If a component fails to load, the page is still complete.
  • Headings are in order, and each page has one main heading. Navigation, content and footer are marked up as page regions.
  • Russian terms carry a language attribute, so speech synthesisers pronounce them correctly.

Forms

  • Every field has a visible label. Errors are described in words, not only by colour.
  • There is no time limit for filling in a form.
  • We do not use picture CAPTCHAs.
  • A multi-step form never asks for the same information twice.

Known limitations

  • There has been no formal audit against WCAG 2.2 and GOST R 52872-2019 by outside experts. We test with automated tools, the keyboard and the NVDA and VoiceOver screen readers, but we may have missed something.
  • Some interactive diagrams, such as the implant assembly, are hard to use with a screen reader. They have a text version, but it is less visual.
  • There is no video on the site yet. If we add video, it will have subtitles and a transcript.
  • The English site follows the Russian one, so accessibility may lag behind on some pages.
  • Documents from other organisations, such as clinical guidelines and research papers, may not be accessible. We cannot change them.

Reporting a problem

Is something hard to read, or does it not work with a keyboard or screen reader? Write to info@osteoplusx.ru with the subject “Accessibility”. Please include:

  • the page address;
  • what you were trying to do and what went wrong;
  • your device, browser and any assistive software.

We reply on working days, within 24 hours, and aim to fix the problem in the next update. Please do not include health information: we process only what we need to reply[4]4Федеральный закон № 152-ФЗ «О персональных данных» — КонсультантПлюс, 2006To the list of sources →.

This address is for questions about using the site. The navigator is not a doctor: diagnosis and treatment stay with your own doctor.

Keeping the site accessible

We check accessibility with every site update. Before new pages go live, we check contrast, heading order, image descriptions and keyboard use. We review this page at least every 12 months.
