The project # About Barrierefrei² Accessibility isn’t an extra – it’s quality. Barrierefrei² helps you understand it and put it into practice. ## Why “squared”? Accessibility works twice over: it opens digital products to people with disabilities – and makes them better for everyone at the same time. Plain language, good contrast and solid keyboard support also help in bright sunlight, with a broken arm or on a train with a patchy connection. ## What you’ll find here - The [WCAG guide](https://barrierefreihochzwei.de/en/wcag) explains every WCAG 2.2 success criterion in plain words – with practical tips and the W3C’s original wording. - The [blog](https://barrierefreihochzwei.de/en/blog) goes deeper: basics, law, design and development, content and testing. - All content is available in English and German. ## Who’s behind it Barrierefrei² is a project by Dennis Wagner, a UX designer focused on UX strategy and accessibility. The website is built the way it recommends: semantic HTML, visible focus, sufficient contrast, dark mode and a menu that lets you adjust font size, contrast and motion. ## Please note Articles on legal topics are for general information and are not legal advice.
