== `+content_css_cors+`

IMPORTANT: This option has been marked as *deprecated*. It will be completely removed in the upcoming {productname} 9.0 release. As an alternative, we recommend using xref:tinymce-and-cors.adoc#crossorigin[`crossorigin`] instead.

When `+content_css_cors+` is set to `+true+`, the editor will add a `+crossorigin="anonymous"+` attribute to the link tags that the StyleSheetLoader uses when loading the `+content_css+`. This allows you to host the `+content_css+` on a different server than the editor itself.

*Type:* `+Boolean+`
