Barrierefreiheit im Web: Warum Accessibility 2026 Pflicht ist
Short: Barrierefreiheit ist kein 'Nice-to-have' mehr.
Barrierefreiheit ist kein 'Nice-to-have' mehr. Mit dem European Accessibility Act (EAA) wird sie gesetzliche Pflicht. Wir zeigen, wie du deine Website für alle zugänglich machst.
Stell dir vor, du betrittst ein Geschäft, aber die Tür ist verschlossen. Genau so fühlen sich Millionen Menschen mit Behinderungen täglich im Internet.
Barrierefreiheit (Accessibility, a11y) bedeutet, Websites so zu bauen, dass jeder sie nutzen kann – egal ob blind, gehörlos oder motorisch eingeschränkt.
Und seit Juni 2025 ist das durch den European Accessibility Act (EAA) für viele Unternehmen gesetzliche Pflicht.
Was ist der European Accessibility Act (EAA)?
Accessibility is no longer a 'Nice-to-have'.
Leaders exploring Accessibility in the Web: Why Accessibility 2026 is mandatory can use Data Analytics & Business Intelligence, Discover solutions sowie IT Security as structured entry points.
Eine EU-Richtlinie, die Barrierefreiheit für E-Commerce, Bankdienstleistungen und digitale Produkte vorschreibt. Wer sich nicht daran hält, riskiert Bußgelder und Abmahnungen.
Aber viel wichtiger: Du schließt 15-20% der Bevölkerung aus.

1. Perceivable (Wahrnehmbar)
Short: Informationen müssen für alle Sinne verfügbar sein.

3. Understandable (Verständlich)
Short: Inhalte und Bedienung müssen klar sein.

4. Robust (Robust)
Der Code muss sauber sein, damit er von Assistive Technologies (Screenreader) interpretiert werden kann.

- ✅ Semantisches HTML: Nutze
