Adaptable  Content can be interpreted whether formatting is on or off.  The structure of the website is consistent throughout and not controlled through the stylesheet.
  5. 5. @radkitten abergmann@atnetplus.c om Perceivable Continued Distinguishable  Content must have contrast from other portions of the website.  Ability to pause and play video.  If color has meaning (red meaning stop, green meaning go) then additional descriptions should be provided.

  10. 10. @radkitten abergmann@atnetplus.c om Wordpress and accessibility WordPress on it’s own is decently accessibility friendly. There are a few issues, but most of them can be fixed either by yourself or through a plugin. The issues are:  An empty search does not return an error unless told to by the theme developer.  “Read More” links are not specific.  Redundant title attributes.
  11. 11. @radkitten abergmann@atnetplus.c om Plugins and themes The vast majority of issues stem from the fact that there is no accessibility check on themes and plugins. Accessibility friendly themes and plugins are few and far between, but they do exist. A great resource for themes & plugins is: http://wp-accessible.org/
  12. 12. @radkitten abergmann@atnetplus.c om Theme options The list cultivated by WP Accessible is by far the best I have found, they have links to the following options through Github:  Accessible default Genesis child theme  Accessibility changes to the Twenty Twelve theme  WordPress Skeleton theme  Child theme for TwentyTenFive

Frontend:  WP Accessibility  Accessible Twitter feed widget for WordPress  Yoast WordPress SEO Plugin  Fast Secure Contact Form  Captcha by BestWebSoft Backend:  Ozh’ Admin Drop Down Menu  MCE Accessible Language Change  Faster Image Insert
  14. 14. @radkitten abergmann@atnetplus.c om WP Accessibility  Remove redundant title attributes from page lists, category lists, and archive menus.  Enable skip links with WebKit support by enqueuing JavaScript support for moving keyboard focus.  Add skip links with user-defined targets.  Add language and text direction attributes to your HTML attribute  Remove the target attribute from links.  Force a search page error when a search is made with an empty text string.  Remove tabindex from elements that are focusable.  Strip title attributes from images inserted into content.  Add post titles to standard “read more” links.  Add a :focus outline to focusable elements.  Toggle for high-contrast and large font stylesheets  Custom admin stylesheet  Provide color contrast testing tool to compare colors against WCAG contrast standards
