You can also use this field to add valid values that belong to [`script-src-attr`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/Content-Security-Policy/script-src-attr), [`script-src-elem`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/Content-Security-Policy/script-src-elem), [`style-src-attr`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/Content-Security-Policy/style-src-attr) and [`style-src-elem`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/Content-Security-Policy/style-src-elem), such as `unsafe-hashes` and `unsafe-inline`.

For example, if you have an external library that adds scripts or inline styles to some HTML elements of the page, you can add `unsafe-inline` to tell the browser that they are safe to render.

```js title="astro.config.mjs"
import { defineConfig } from 'astro/config';

export default defineConfig({
experimental: {
csp: {
styleDirective: {
resources: [
"'unsafe-inline'"
]
},
scriptDirective: {
resources: [
"'unsafe-inline'"
]
}
}
}
});
```

After the build, `style-src` and `script-src` directives will contain the `'unsafe-line'` resource:

```html
<head>
<meta
http-equiv="content-security-policy"
content="
script-src 'unsafe-line';
style-src 'unsafe-line';
"
>
</head>
```
