Note: This release is in preview. Features described here don’t become generally available until the latest general availability date that Salesforce announces for this release. Before then, and where features are noted as beta, pilot, or developer preview, we can’t guarantee general availability within any particular time frame or at all. Make your purchase decisions only on the basis of generally available products and features.

Overriding Standard Tokens (Deprecated)

If you override design tokens for your custom components, replace them with SLDS styling hooks.

Overriding standard tokens is deprecated as of API version 61.0, the Summer ’24 release. We recommend that you use Styling Hooks instead. See Replace Design Tokens with Styling Hooks.
