Come leggere i dati dei report
• Grazie all’analisi svolta con il tool “
Accessibility Insights for Web” (prime pagine di ogni
sezione) è stato possibile individuare gli errori presenti nella gerarchia dei contenuti (segnalati con
dei punti e linee disposte su tutta la pagina). I punti di riferimento identificano, a livello di codice,
le sezioni principali di una pagina. Le persone che utilizzano lettori di schermo e altre tecnologie
assistive utilizzano punti di riferimento per trovare contenuti pertinenti. In caso di una gerarchia
non lineare, i numeri non seguono un ordine cronologico, ma casuale.
• Grazie all’analisi svolta con il tool “
IBM Equal Access Accessibility Checker
” (tabelle) è stato
possibile individuare, per ogni riga di codice, la violazione di uno o più criteri legati
all’accessi-bilità. In particolar modo il tool segnala che tipo di principio è stato violato e suggerisce come
risolvere il problema.
• Grazie all’analisi svolta con il tool “
Mauve++
” (tabella grafica) è stato possibile individuare, in
maniera immediata, il numero di violazioni presenti sulla pagina e il numero di criteri conformi
alle linee guida WCAG.
