  The `sx` prop provides a lot of power, which means it is an easy tool to abuse. To best make use of it, we recommend following these guidelines:
  -* Only use the `sx` prop for small stylistic changes to components. For more substantial changes, create your own wrapper using `styled-components`.
  +* Use the `sx` prop for small stylistic changes to components. For more substantial changes, consider abstracting your style changes into your own wrapper component.
  * Use [system props](/system-props) instead of the `sx` prop whenever possible.
  * Avoid nesting and pseudo-selectors in `sx` prop values when possible.
