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.
