[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.

Inizia individuando i componenti Accordion e Tabs utilizzati nella barra laterale e nei blocchi di codice, quindi confronta il loro comportamento con i riferimenti di Radix e ReachUI collegati nell’issue. Il lavoro è completato quando le interazioni da tastiera elencate e i requisiti relativi a button, heading, aria-expanded e aria-controls sono stati soddisfatti per entrambi i componenti.
