Other Features and Advice:
Images on cnib.ca have alternative text attributes, often known as alt text. This means that when an image is used on a web page to convey information its content is also described in the alt text. This means that the image can be understood by text browsers and assistive technologies such as screen readers. If an image is used for simply decorative purposes, the text attribute for the image is left empty in line with accepted best practice.
Given current advancements in technology, the use of Flash animation technology with a screen reader is now possible. Where Flash is featured on cnib.ca, it has been made accessible. For an example, see the AMD Challenge interactive flash module.
Colour Reliance and Image Alternatives
The cnib.ca website was created with colour impaired visitors in mind. The site was designed and was tested to conform to minimum contrast requirements for visitors with colour-blindness or other ocular impairments that could prevent them from reading text that does not have sufficient colour contrast with background colours. WCAG 2.0 level AA requires a contrast ratio of 4.5:1 for normal text and 3:1 for large text.
The cnib.ca website uses images in a strong and effective method for communication. Where visitors cannot view images, due to visual or technological issues, alternative text is provided to ensure that the content of those images - where relevant - is communicated to the visitor. When images are disabled for any reason, the entire site was built to be fully navigable and usable.
The website never relies exclusively on colour or image to convey information.
Scripting Languages and Device Independence
Device Independence simply refers to the idea that cnib.ca does not require the use of any specific piece of browser software or operating system. The site can even be navigated using a wireless device (i.e. Android or iPhone).
