Accessibility Statement

The power of the Web is in its universality. Access by everyone regardless of disability is an essential aspect.

~ Tim Berners-Lee, inventor of the Web and Director of the World Wide Web Consortium (W3C) is committed to providing a website that is accessible by the widest possible global audience.

We adhere to the principles and guidelines of responsive web design (RWD), which enables content to display neatly across multiple browsers and devices.

Also, every page on this site provides a language translation tool, making our content readable in many languages.

This website is also accessible to people with disabilities:

  • We know that many people live with varying degrees of blindness, deafness, photosensitivity, cognitive impairment or another disability. In some cases, it's a combination of disabilities.
  • Below are some of the steps we've taken to ensure that most, if not all, people with disabilities have access to the content on this site.

If you encounter any difficulty using this site, or have a suggestion that may help us improve accessibility (or something else), please contact us.

Adherence to Web Standards & Best Practices

This website adheres to various W3C Web Standards.

This includes the Web Content Accessibility Guidelines 2.0, a widely-adopted standard for making content accessible on the web. Our web pages satisfy all guidelines for Level A and Level AA conformance.

This website also adheres to the HTML and CSS standards to ensure that our content is always complete and accessible regardless of platform, browser or device.

We also endeavor to follow industry best practices, such as separating content from presentation and using valid, semantically-meaningful mark-up.

Alternative Text for Images

There may be two types of images on this site: (1) images that convey information, and (2) images that are purely decorative.

Images that convey information include text equivalents in the HTML alt attribute.

"Alt text", as it is known, ensures that meaningful images that cannot be seen have an alternative way to convey the information they provide.

This helps people who are blind, or have images disabled in their browser, or have a text-only browser, or use text-to-speech software, among other possibilities.

Examples of meaningful images include pie charts, company logos, maps, and images of text. Without alt text this information would be inaccessible to many people.

Images used only for decoration, such as a background design, don't need alt text, but include empty alt attributes (alt=""), for improved processing by assistive technology.

Images sourced in the CSS do not provide alt text as they are almost always purely decorative. In the rare instance where a CSS-sourced image happens to serve a greater purpose (e.g., a clickable icon rendered as a pseudo-element), we include a text equivalent in the title attribute of the target HTML element.

Avoiding Use of Color Alone to Convey Information

Some people are color-blind or have another vision limitation that prevents them from distinguishing between colors. Some people use text-only browsers. For these reasons we avoid conveying information with color alone.

Wherever color has meaning on this site, the information is also conveyed by other means, such as text, patterns, underline, bold or italics.

High Contrast Between Text and Background

When the contrast between text and background is too low, people with low vision or color deficiencies may have difficulty reading the information.

We have selected color combinations for this site that exceed the WCAG 2.0 recommendation for a minimal contrast ratio.

The high contrast we provide between text and background should make it possible for people with moderately low vision and any degree of color blindness to read the information.

Meaningful Link Text

Links on this site are clear and concise, and are designed to make sense out of context.

A person reading a link on this site should have no problem understanding its purpose, even if all surrounding text were to be removed.

Links that can benefit from more details than provided by the link text alone also have a title attribute, which displays a tooltip on hover.

Text links that take a user to another website provide a visual cue ( link to another website ).

Re-sizable Text

Text on this site can be easily resized. If you would prefer the text size to be larger or smaller simply adjust your browser preferences.
