Website content (text, links, images, attachments, videos etc.) must be fully accessible.

Below are simplified rules to help users when providing us with new content; please refer to the WCAG 2.1  guidelines for complete rules.

Images

  • Images must have a meaningful text alternative (description)
  • Images that include text as part of the image must have a suitable text alternative, with the exception of logos
  • Infographics and charts must have a link to a full description of the content

Links

  • Links must use some text that is meaningful out of contex: users of screen readers must be able to understand the link without reading the surrounding text. Avoid 'click here' and 'read more'.
  • Links must not typed out in full (starting with http or www), but instead be embedded within text.
  • All links must open in the same browser window

Documents

Text documents

Word documents and PDFs must be fully accessible

  • Documents must have a title and hierarchical headings
  • Heading styles must not be used to highlight information
  • Bold text should be used a little as possible, and should not be used as a substitute for headings
  • Do not use colour as the sole way to convey important information
  • Images must follow the rules stated above
  • Links must use text that is meaningful out of context (see above), and not typed out in full

In addition to those recommendations, please follow our guidelines Writing for the web

More information is available on the UK Government page on Guidance how to publish acccessible documents

Tables

Tables must follow the recommendations for text documents

Additional recommendation for tables:

  • Tables should include a header row.
  • Empty cells within a table should be marked as such with a minus sign, a zero or N/A
  • Avoid merging data or header cells; merged cells cause navigation problems

Additional recommendation for presentations (either powerpoint or PDF)

  • Use unique slide titles, to allow screen readers to skim slides to navigate
  • Make hyperlinks, images and tables accessible: see recommendations above
