Accessibility for the website
»The power of the web lies in its universality. Access for all people, regardless of a disability, is an essential aspect.«
Tim Berners-Lee, W3C Director and inventor of the World Wide Web

One of the fundamental principles of digital accessibility is to design websites, software, and digital media in a way that flexibly adapts to the various needs of users, their preferences, or personal situations.
Everyone benefits from high user-friendliness and a good "user experience," but for many people, digital accessibility is a necessary requirement; otherwise, they cannot participate in everyday life.
The EU Directive 2016/2102 requires all public authorities in Germany to make their websites and mobile applications accessible, meaning they should be usable by all people - regardless of their physical or mental abilities. This also specifically applies to universities.
