<p>O ARIA define as semânticas que podem ser aplicadas aos elementos, e são divididas em <strong>funções</strong> (definindo um tipo de elemento da interface do usuário) e <strong>estados</strong> e <strong>propriedades</strong> que são suportados por uma função. Os autores devem atribuir uma função ARIA e os estados e propriedades apropriados a um elemento durante seu ciclo de vida, a menos que o elemento já possua semântica ARIA apropriada (através do uso de um elemento HTML apropriado). A adição de semântica ARIA apenas expõe informações extras para a API de acessibilidade de um navegador e não afeta o DOM de uma página.</p>
