Kurze Einordnung des aktuellen automatischen Scans mit den wichtigsten Signalen zu Status, Problemen und Entwicklung.
science-lab.org erreichte im neuesten automatischen Scan vom 07.04.2026, 03:13 den Status Kritisch bei einem Score von 2.
Auffällig waren vor allem Probleme in den Bereichen Kontrast und Navigation. Insgesamt wurden 36 Probleme in 3 Kategorien erkannt.
Kontrastprobleme erschweren vor allem das Lesen kleiner oder weniger hervorgehobener Texte und fallen auf hellen Flächen oft zuerst auf. Mehr dazu im Themenartikel Kontraste .
Der Eintrag basiert auf einem automatischen Scan und dient als Orientierung. Für eine verlässliche Gesamtbewertung der Barrierefreiheit bleibt eine manuelle Prüfung wichtig.
