Standards compliance

  1. All pages on this site are designed to comply with all priority 1 guidelines of the W3C Web Content Accessibility Guidelines. Many of the priority 2 and 3 guidelines are also complied with. The developers of this learning site will continue to review and seek to extend compliance with these and other accessibility guidelines.
  2. All pages on this site are designed to be written in well-formed, valid XHTML and CSS.
  3. All pages on this site use structured semantic markup. H1 tags are used for section titles, H2 tags for main page titles (and H3 and H4 tags for sub titles). Certain specialist browsers, such as screen readers like Jaws, allow users to navigate through pages by headings and sub-headings when they are properly marked-up in this way.

Navigation aids

Every content page on this learning site begins with an invisible 'Skip to content' link which allows users of text only and screen reader browsers to skip over page headers and navigation bars and go straight to the main content.


  1. Many links have title attributes which describe the link in greater detail, unless the text of the link already fully describes the target (such as the title of a page or section).
  2. Links are written to make sense out of context.


All content images used in this site include descriptive ALT attributes. Screen readers read will read this text, and text-only browsers will display it so that, at the very least, users who have problems seeing images can access a sense of what the images are communicating. Purely decorative graphics include null ALT attributes.

Visual design

  1. This site uses cascading style sheets for the majority of its visual layout and text formatting.
  2. The size of almost all of the text on this site can be manipulated by users via the 'text size' options in visual browsers. All key content, all body text and of all of the text contained in navigation menus can be increased or decreased by users.
  3. If your browser or browsing device does not support stylesheets at all, the content of each page is still readable.

Tables and forms

  1. All of the input elements in the forms on this learning site are marked up with label tags. These provide several benefits:
    - Users who have difficulty navigating through a form with a mouse can, for example, click on the text beside the form elements, such as text input boxes and check boxes, in order to enter those elements. All of the tests within the learning area have this feature, so that in multiple choice tests, users can click on the answers themselves in order to select them, rather than only in the small check boxes.
    - The use of label tags allows screen readers to intelligently announce what a particular input element is, by reading the label.
  2. All tables containing key content are marked with a summary, so that screen readers and speech browsers read a description of the contents of tables when they first come across them.
