## Dynamic values

For highly dynamic CSS values, we recommend using inline CSS variables instead of passing an object with varying values to the `sx` prop on each render.

Check warning on line 297 in docs/data/system/getting-started/the-sx-prop/the-sx-prop.md

[vale] reported by reviewdog 🐶 [Google.We] Try to avoid using first-person plural like 'we'. Raw Output: {"message": "[Google.We] Try to avoid using first-person plural like 'we'.", "location": {"path": "docs/data/system/getting-started/the-sx-prop/the-sx-prop.md", "range": {"start": {"line": 297, "column": 32}}}, "severity": "WARNING"}
This approach avoids inserting unnecessary `style` tags into the DOM, which prevents potential performance issues when dealing with CSS properties that can hold a wide range of values that change frequently—for example, a color picker with live preview.

:::info
If you're having problems with your Content Security Policy while using inline styles with the `style` attribute, make sure you've enabled the [`style-src-attr` directive](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Content-Security-Policy/style-src-attr).
Visit the [Content Security Policy guide](/material-ui/guides/content-security-policy/) for configuration details.

## TypeScript usage

A frequent source of confusion with the `sx` prop is TypeScript's [type widening](https://mariusschulz.com/blog/literal-type-widening-in-typescript), which causes this example not to work as expected:
