"y") em desenvolvimento web significa permitir que o maior número possível de pessoas possam usar sites, mesmo quando as habilidades dessas pessoas são limitadas de alguma forma.</p> <p>Para muitas pessoas, a tecnologia torna as coisas mais fáceis. Para pessoas com deficiência, a tecnologia torna as coisas possíveis. Acessibilidade significa desenvolver conteúdo para ser o mais acessível possível, não importando as habilidades físicas e cognitivas de uma pessoa e como ela acessa a web.</p> <p>"<strong>A web é fundamentalmente projetada para funcionar para todas as pessoas</strong>, independentemente de seu hardware, software, idioma, localização ou capacidade. Quando a web atinge esse objetivo, ela é acessível a pessoas com uma gama variada de audição, movimento, visão e capacidade cognitiva."
