Overall graphic communication design

We aimed to make the overall graphic communication design of this website accessible and usable, that builds on best practice guidelines and research. We have also structured this website and the navigation bar, into clear parts.

For people with dyslexia

This website’s dyslexia-friendly design features:

  • Simple design and layout (decreased clutter).
  • Avoided underlines on hyperlinks.
  • Slightly larger body text typeface size than normal.
  • Specially designed dyslexia typefaces (Sylexiad Serif and Sylexiad Sans) based on testing with people and Robert’s PhD A typeface for the adult dyslexic reader.
  • Medium length text line width (68 characters with word spaces included).
  • Ranged-left justification (no hyphenation).
  • Half a body text leading between paragraphs.

Language translation

If you cannot read this website because the text is not written in a language you understand, we recommend using Google Translate.

Website accessibility

Our webpages pass many of the W3C (World Wide Web Consortium) web content accessibility guidelines (WCAG) 2.0 requirements at levels A, AA and AAA. We also used the WAVE Web Accessibility Tool. This website has also been tested using the ChromeVox screenreader software and the VoiceOver accessibility option on a Mac.

Other accessibility features of this website include:

  • Logical and consistent coding and sectioning for webpage code and design.
  • Logical and consistent navigation for keyboard users.
  • A skip navigation link for screenreader and keyboard users.
  • We also mainly adhere to the A11Y Project checklist (in February 2022), except for the issue of (use only one h1 element per page).
  • Relevant and descriptive alt tags for images.
  • HTML landmark elements.
  • Zoomable.

PDFs [Problem Document Files]

We self-host quite a lot of PDF files, and we are aware they are not very accessible. Instead we have tried to make images available of the PDF pages, and although they are still not ideal for screenreaders, we have tried to describe the content within images relevantly and descriptively using alt tags, which should help a lot more.
