  • Shorter line lengths and narrower text columns make reading easier.
  • Consider setting a percentage width for text areas and set the margins to “0 auto” via CSS. The page side margins will then increase proportionately on wider screens.
  • Most browsers have a default line-height of around 1em. This normally results in closely packed lines of text. Increasing the line-height to around 1.3em immediately makes longer lines of text easier to read. Likewise, ensure that paragraphs are visibly separated. Don’t be afraid of white space. Use it to enhance readability.

  • percentages or ems.
  • If possible, use a sans-serif font. The decorative “hooks” on the main strokes of serif letters may create additional problems for dyslexic users.
  • If you have to use a corporate serif font, consider reducing the letter-spacing slightly so that the letters within a word lie closer together but increasing the word-spacing to create a slightly larger distance between individual words.
  • uneven word spacing disrupts that pattern recognition.
  • Unjustified text, although less attractive at first glance. is far easier to read.
  • When italic fonts are used on a web page, the individual letters can have a slightly jagged line compared to a non-italic font. This “pixelation,” coupled with their “lean to the left” makes them hard for a dyslexic person to read. The effect is compounded if the text is also small.
  • Use italics sparingly and consider bold text for important words. They’ll be far easier to read.
  • Photographs, charts and icons can convey a great deal of information regarding the topic of a page. Graphics can break the page up into smaller chunks. They can also provide visual memory aids and support comprehension for dyslexics.
  • Dyslexics often have poor organisational skills. Lists can help them by organising information into small, logical chunks.
  • Dyslexics tend to have poor information processing skills. So it is relatively easy to overload them by literally providing too much information on one page.
  • Within a page, use headings to sub-divide the page logically and visually. Adding coloured heading backgrounds or borders will act as further support.
  • Consider breaking complex pages down into two or three smaller pages.
  • Keep site navigation simple and logical. Make sure that the Home page is easily reachable from any part of the site. Try not to “hide” this important link in a logo.
  • break long sentences down into two or more shorter sentences
  • Many designers do not realise that some screen reader users can see perfectly well. It is not uncommon for dyslexics to use screen readers to support their reading. This may create problems where text has been positioned off screen.
  • If you do make use of off screen positioning, try to do so sympathetically. Consider the viewpoint of those who can both hear the screen reader and see the page. Ask yourself if you’re potentially creating confusion.

  • Christian asks what would be the open-source equivalent of AIR? XUL says Ian. Christian says that AIR is built on HTML, CSS and JavaScript so once the player gets keyboard access it will be quite accessible. Ian responds that he looked on the Adobe site for accessibility info on AIR and the fact that he found nothing scared him.

  • links are more useful when they make sense out of context
  • In most cases, it is better to use human-readable text instead of the URL.
  • The alternative text should convey the content of the image and the function of the link. In most cases, the content of the image and function of the link are the same, so this text can be very succinct (e.g, alt="Products").
  • ...6 more annotations...
  • When images are used as links, the alternative text performs the function of link text.
  • on both mouse hover and keyboard focus
  • they are also accustomed to seeing tabs and main navigational features (oftentimes created as graphics rather than text) without underlining. In these cases, the linked items should be designed so it is apparent that the user can click on them to perform an action.
  • Authors should avoid non-informative link phrases such as: click here here more read more link to [some link destination] info
  • adjacent links should have adequate whitespace (such as link CSS margins) between them to minimize users inadvertently clicking the wrong link
  • an alphabetical index may use each individual letter of the alphabet as a link
