# ARIA Labelled By

![](/files/BMrxiWSIB0fSSIMhGWeP)

### Problema

Vimos na seção anterior que os IDs para os elementos em uma página precisam ser únicos. Quando utilizados com o atributo `aria-labelledby` isso se torna ainda mais importante.

O atributo `aria-labelledby` é usado para indicar aos leitores de tela e ferramentas assistivas qual o rótulo para determinado elemento. Isso é feito usando os IDs dos elementos. Caso os IDs esteja duplicados, os leitores poderão indicar o valor errado para o rótulo, prejudicando a navegação de pessoas com tais problemas.

{% code title="Código com problemas" %}

```html
<div role="tabpanel" aria-labelledby="tabpanel-label">
    <h2 id="tabpanel-label">
        Tab panel title
    </h2>
    <p id="tabpanel-label">
        Lorem ipsum dolor sit amet, consectetur adipiscing elit,
        sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
    </p>
</div>
```

{% endcode %}

### Recomendações

Garanta que todos os atributos `id` da página são únicos e que os atributos `aria-labelledby` estejam referenciando o elemento correto.&#x20;

{% code title="Código corrigido" %}

```markup
<div role="tabpanel" aria-labelledby="tabpanel-label-title">
    <h2 id="tabpanel-label-title">
        Tab panel title
    </h2>
    <p id="tabpanel-label">
        Lorem ipsum dolor sit amet, consectetur adipiscing elit,
        sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
    </p>
</div>
```

{% endcode %}

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://partners.tray.com.br/themes/construindo-seu-template/core-web-vitals/acessibilidade/aria-labelled-by.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
