Skip to content

This feature allows the user to skip over the repeated content at the beginning of each page (such as the heading and navigation) and go straight to the main page content. This is especially useful to those with screen readers because it gives the user a way to avoid listening through lengthy menus every time he or she enters a new page.

Alternative text

Images on 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.

Colour reliance and image alternatives

The TTC 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. Colour reliance and contrast requirements on the TTC web site have been designed to comply with the Web Content Accessibility Guidelines (WCAG) Level AAA standard.

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

The TTC website was created using only standard web technologies. The website requires no special scripting languages or plug-in software to navigate or use. Where JavaScript has been used for enhanced features, those features are hidden when a visitor has JavaScript disabled or does not have the appropriate version.

Tables are used for tabular data only

Tables are not used for layout within the TTC website. Tables are only used to present data or information which is best displayed using columns and rows.
