Our site conforms to W3C's Web Content Accessibility Guidelines 1.0, level A.
Below there's a list of critical requirements, which alone cover nearly 40% of highlighted by W3C accessibility problems. These have been given extra attention and highest priority during expert evaluation.
- Provide a text equivalent for every non-text element
- Ensure that foreground and background colour combinations provide sufficient contrast when viewed by someone having colour deficits or when viewed on a black and white screen
- Ensure that pages are usable when scripts, applets, or other programmatic objects are turned off or not supported. If this is not possible, provide equivalent information on an alternative accessible page
- Until user agents allow users to freeze moving content, avoid movement in pages
- Until user agents allow users to turn off spawned windows, do not cause pop-ups or other windows to appear and do not change the current window without informing the user
- Divide large blocks of information into more manageable groups where natural and appropriate
- Clearly identify the target of each link
- Use the clearest and simplest language appropriate for a site's content
Menu links are grouped and an option to bypass navigation is provided. Link to skip navigation has no visible anchor text, and is provided specifically for people using a screen reader.
Most browsers support jumping to specific links by typing keys defined on the website. The following access keys are available throughout site:
- 1 - Home page
- 3 - Site map
- 9 - Contact us
- 0 - Accessibility statement
- T - Top of the page
Wherever possible, they do not conflict with commonly-used screen reader and browser keyboard shortcuts.
Access keys are selected in different ways in different browsers:
- Mozilla Firefox:
Press ALT + SHIFT + the access key.
- Google Chrome:
Press ALT + the access key.
Press Shift + Esc to toggle into Access Key mode, then press the access key. Shift + Esc must be pressed each time you want to use an access key.
- Internet Explorer:
Press ALT + the access key, then Enter.
Press CTRL + the access key.
- This site uses cascading style sheets for the most aspects of visual layout.
- Users of Mozilla Firefox, Google Chrome, Opera and other browsers may use control++ to increase the text size and control+- to decrease it.
- If your browser or browsing device does not support stylesheets at all, the content of each page is still readable.
Structured, semantic markup is used to represent document structure. H1 tags are used for main titles, h3 tags for subtitles, and so on.
- Many links have title attributes which describe the link in greater detail, unless the text of the link already fully describes the target (such as the headline of an article).
- Links are written to make sense out of context.
- Links which go to external websites are clearly identified as such.
Descriptive and meaningful text equivalents are provided for all content images, graphical buttons, symbols and objects. Images are not used to represent text, all headings are styled with the help of CSS and can be resized to suit users needs.
Website design has been tested against colour contrast to ensure that all information is still clear.
Most of the text is written as grey on white and is perfectly contrasting. Grey on white combination passes colour visibility test successfully:
- The difference in brightness between the two colours is sufficient. The threshold is 125, and the result of the foreground and background colours is 169.
- The difference in colour between the two colours is sufficient. The threshold is 500, and the result of the foreground and background colours is 501
