[Beta] Inaccessible UI Components

Accordion a11y issues

• When an Accordion trigger is focused, pressing down/up should focus the next/previous trigger.
• When an Accordion trigger is focused, pressing space should expand/contract its panel.
• The Accordion trigger should be a <button> rather than a <a>.
• The Accordion trigger should be wrapped in a h tag.
• The Accordion trigger should have an aria-expanded attr set to true when open.
• The Accordion trigger should have an aria-controls attr.

The same goes for the Tabs component (found in the sidebar and on code blocks), it fails a11y in many ways. I'd suggest you look at UI libs like Radix or ReachUI which provide high-quality, accessible UI components.

Comece localizando os componentes Accordion e Tabs usados na barra lateral e nos blocos de código; em seguida, compare o comportamento deles com as referências do Radix e do ReachUI vinculadas na issue. O trabalho estará concluído quando as interações de teclado listadas e os requisitos de button, heading, aria-expanded e aria-controls forem tratados para ambos os componentes.
