Checklist for editors

In addition to programming the website, it is important to make the content of a website (text and images) barrier-free. The foundation "Access for All" has developed a  Checklist for Editors which supports editors in the daily creation of web content.

The checklist is categorized according to the different content types of a website:

• text content
• alternatives for graphical content
• spreadsheets
• lists
• links
• color use
• multimedia content
• intelligibility
• accessible PDF document

Information on creating accessible PDF documents can be found in the PDF-Workshop on the website of the foundation "Access for All."
