# Aura Components in `ui` Namespace (Deprecated)

:::note
Most of these Aura components have Lightning Web Component (LWC) equivalents available. Use LWC components where possible for new development. Refer to the [LWC documentation](/docs/platform/lightning-component-reference/guide/lightning-accordion.md) for the corresponding components in the `lightning` namespace.
:::

The `ui` namespace has been deprecated. It presents a collection of base components that provides basic user interface elements without implementing styles from Salesforce Lightning Design System (SLDS).
