The Toolbox is designed to comply, with all priority 1 guidelines of the W3C Web Content Accessibility Guidelines.
The navigation utilises access keys for each Task page. Task 1 uses Access key 1, Task 2 uses Access key 2 and so on.
Flash MX 2004 has been used to build Flash assets – improved vision-impaired accessibility over previous version; however it's only accessible to screen readers on Windows, not Mac. Printer friendly versions of all Flash assets are provided to counter this, and as an alternative for low-bandwidth users.
All content images used in this site include descriptive ALT attributes . Purely decorative graphics include null ALT attributes.
Complex images include LONGDESC attributes to explain the significance of each image to non-visual readers.
The main navigation bar inside the Unit uses JavaScript. If JavaScript is not enabled then a text version of the navigation will appear instead. If a user has JavaScript enabled but still wishes to use a text version of the navigation (perhaps a user whose screen reader has problems with JavaScript) there will be (post proof of concept) a link to the text version above the navigation.
There is a skip navigation link in the navigation which allows users to skip straight to the content. It is rendered invisible to not distract from the visual style of the pages but can be accessed by tabbing.
To move from link to link, the Tab key can be used to navigate around the site without the need for a mouse. For additional ease of use, a logical tab index system has been included in the website.
The Toolbox uses CSS (cascading style sheets) for visual layout; will use only relative font sizes, compatible with the user-specified "text size" option in visual browsers.
