accessibility
       b
New exciting web
technologies enable
us to do more
accessible
web sites
by doing less.
HTML4
HTML4
HTML5
We need to
get rid of
the dogmas.
Responsive Web
         Design
+ universally works on every screen size
+ simplifies layout for users who need extremely
low screen resolutions (screen magnifying)

- di cult to implement if your project is complex
Robust
Web fonts
+ readable by screen readers
+ resizable
+ easy to implement

- di cult to read for mentally challenged people
- slight performance penalty
Perceivable
Forms
+ validation before sending means less errors
+ required, invalid and disabled visible to SR
+ input according to the type attribute
+ easy to implement

- own validation may interfere visually
- mind that post codes are not numbers
Understandable
Audio &Video
+ HTML controls increase accessibility
+ adding subtitles is easy
+ users are in control of autoplay1

- multiple formats needed (ogg/webm + mp4)


(1 Not yet implemented, but possible.)
Operable
It’s hard to reach


Perfection
and when you do, it is often
   destroyed by others.
We’ll help!
