The different types of disabilities and how we can help:

Visual disabilities

  • Consider Structure and semantic mark-up separate from presentation
  • Design & colour may be perceived differently
  • Don’t rely on colour to convey meaning - it may be missed
  • Avoid too small text
  • Lack of keyboard support
  • Alt tags

Auditory impairments

  • Captions for video
  • Adjustments for captions
  • Transcripts for audio

Cognitive, learning and neurological disabilities

  • Structure is important
  • Consistent labelling
  • Predictable functionality
  • Different methods of navigation e.g. search
  • May use text to speech
  • May adjust text & spacing
  • Simple layouts
  • Break up text with images to break content up
  • Options to disable motion & animation

Physical and motor disabilities

  • Keyboard support
  • Large clickable areas
  • More time to complete tasks
  • Error correction on forms
  • Options to skip things

Speech disabilities

  • Avoid voice only interaction
  • Avoid phone as the only means of communication

Design considerations for accessibilty

Here are some design suggestions for a better experience:

  • Using a skip to main content link. Before the main navigation add a skip to main content link. This link can be hidden using CSS if it’s not focused (Display block when tabbed to. eg .hiddenSkipClass:not(:focus){ display: block;} )
  • Font sizes set at a minium of 16px-20px for body copy. Use ems, rems so that they can scale
  • Use relative units to scale better such as ems, rems, %
  • Headers & use of bold font weight should be distinguishable
  • Avoid all caps
  • Text line lengths should not be too short or long: Ideal length is 45-75 characters , 66 characters is ideal
  • Line height, set at around 125% of the text size
  • Mobile & desktop top touch targets, recommended touch size 44px-48px square. Make them big & give them space
  • Navigation menus give them vertical space
  • Standalone icons should be simple and recognizable. Add text next to them is preferable
  • Motion; Keep it simple. Add option to disable motion for example a fixed toggle control
  • Links with 'read more'. Use more descriptive links, 'read more about XYZ'. Or use a ‘visually-hidden’ CSS class to hide descriptive text
  • Skipping headers & page structure. Headings on well-designed web pages will form an outline of the page’s content.
  • Review


  • Use Asterix for required fields
  • Let users know validation requirements before submitting
  • All form fields need a proper label, not a placeholder
  • Don’t rely on colour alone for errors, use an error message or icon
  • Use native HTML form controls
  • Use buttons instead of span tags

A good accessbility process for developers

  • Identify goals before starting projects
  • Put in charge one person
  • Enforce the accessibility features
  • Evaluate 3rd party frameworks for accessibility before use
  • Have empathy with users with disabilities
  • All developers & designs need to know what it takes to make things accessible
  • Make it part of the process potentially while browser testing
  • Check the WCAG Guidelines
