Accessibility means that websites, apps, and digital content are accessible to everyone, regardless of physical, sensory, or cognitive limitations. The goal is to design digital offerings so that users with visual impairments, hearing problems, motor impairments, or learning difficulties can access them without difficulty.
Who sets the rules for accessibility?
The internationally recognized standards for accessibility are defined by the W3C Web Accessibility Initiative (WAI). The most important guidelines are the WCAG (Web Content Accessibility Guidelines), currently in version 2.1. They provide specific recommendations for:
- Structured content and headings
- Alternative text for images
- Contrast and color schemes
- Usability via keyboard and screen readers
- Captions and transcripts for multimedia
Country-specific regulations
Whether and how accessibility is required by law varies by country:
- Germany: Accessible websites are mandatory for government agencies, public bodies, and certain companies (BITV 2.0, Disability Equality Act).
- Switzerland: The Disability Equality Act (BehiG) and the Web Content Accessibility Guidelines (WCAG-compliant) apply to the federal government, cantons, and public-law institutions.
- EU: Directive 2016/2102 requires public bodies to design their digital services to be accessible, with WCAG 2.1 Level AA as the standard.
- USA: The ADA (Americans with Disabilities Act) may also apply to websites, particularly regarding public accessibility and commerce.
Why Accessibility Is Important
- Expands your website’s reach to users with disabilities
- Improves usability for all users, not just people with disabilities
- Has a positive impact on SEO, as structured and semantic content is better read by search engines
- Meets legal requirements and reduces legal risk
Best practices for accessible websites
- Alt text for all images
- Test contrast and colors
- Clear, consistent navigation
- Captions and transcripts for videos
- Enable keyboard navigation
- Semantic HTML structure (h1–h6, ARIA roles)
Conclusion
Accessibility is more than just a trend—it ensures that digital content is accessible to everyone. By adhering to international standards such as WCAG and complying with country-specific regulations, you can design your website to be user-friendly, legally compliant, and SEO-friendly.
