Web Accessibility

Please review the resources published here and let us know if you have any other additions that may help McMaster community to better their accessibility knowledge and techniques to facilitate a barrier free McMaster community.

McMaster Accessibility Website


There are many tools available to help with the accessibility evaluation of the website. Please note, that these tools should be used in combination with each other to ensure the highest probability of the website's accessibility. Currently there is no single tool that can validate web accessibility.

W3C Markup Validation Tool

This tool is XHTML and HTML validator; it checks the syntax of web pages. It ensures that essentially legal HTML code was used.

Wave by WebAim

This tool provides accessibility evaluation. This tool should be used in combination with the tools listed here. Achieving "no errors" report using this tool does not qualify the website to be considered fully accessible.

Colour contrast checker by WebAim

Enough contrast between text and its background must be provided so that it can be read by people with moderately low vision. A minimum contrast ratio of at least 4.5:1 of text and images of text is required in most cases.

UTS developed WCAG checklist

Checking content for accessibility is a tough job as there are currently no machine validated conformance available.
