Standards Compliance

  • All Web pages are built using standards-compliant HTML5.
  • All pages use structured semantic markup. For instance, each page contains one Header 1 Level Tag, and any appropriate sub-level heading tags. All paragraphs are properly coded with paragraph tags.

Navigation Aids

  • All pages on this site include a consistent set of global main navigation links.
  • Drop down main navigation menus use “Tab” to access drop down submenus. Right and left arrow keys can be used to move from major heading to major heading, up and down arrow keys are a second way to access submenus.
  • A series of shortcuts to skip to the header, content and footer appear when you begin “tabbing” in to the site.
  • All sub-navigation menus will appear below the main navigation menu.
  • Links
  • Wherever possible, links are written to make sense out of context.
  • 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 headline of an article).
  • Many browsers (such as JAWS, Home Page Reader, Lynx, and Opera) can extract the list of links on a page and allow the user to browse the list, separately from the page.
  • If link text is duplicated; eg. “Read more” links, then “title” text is used to distinguish them.


  • All content images used on this site include descriptive ALT attributes. Purely decorative graphics include empty ALT attributes.

Visual Design

  • This site uses Cascading Style Sheets (CSS) for visual layout. Content is independent of CSS.
  • Users may disable CSS or use their own style sheets.
  • Where possible color brightness and illuminosity meet WCAG level 2 standards.
  • Current page focus is highlighted in contrasting colors.
