Web Development: Accessibility Roadmap
The Current State
- The base template is made to comply with Level AA before any implementation. Each website starts out compliant.
- Alt tags are used everywhere. Page decoration and unnecessary images receive empty alt tags.
- Table layouts have been removed, with the fall 2009 template rollout. Some sites remain still needing conversion.
- Web forms carry labels.
- Whenever possible documents are posted as PDF files, the industry standard archiving format of choice. Accessibility my not be ideal, but the documents can be accessed by the majority of site users unlike random formats (cws, wpf, docx, xls, etc.). Scanned files have OCR applied whenever possible.
- Use of java script and flash is kept to a minimum. When used attempts to provide less encumbered alternatives are made.
- New cascading style sheets have been added with the 2009 template. In addition to screen and print 3 additions (handheld, speech, & aural) have been added to attempt to control user experiences in different usage situations
- The propagation of video on the web brings additional challenges. Providing alternate content wether transcripts or subtitles needs to be addressed in a more thorough manner. A suitable platform to control online video efforts and accessible options is needed. The current HTML 5 format war may impact how this plays out(FLV, H264, VP8).
