## CSS Configuration Updates

When updating components, the CLI may also update your CSS variables and Tailwind configuration to ensure compatibility with the latest component versions.

<Callout type="info" title="Configuration Changes">
  Component updates may require new CSS variables or Tailwind configuration
  changes. The CLI will detect your Tailwind version and apply the appropriate
  format automatically.
</Callout>
