* To get TinyMCE skins (ui & content CSS) add them to the `assets` list of your `angular.json` file.
* Add tinymce skins, themes and plugins to the assets property of your `angular.json`. This will allow Tiny to lazy-load everything it requires on initialization.

Note: in most use cases the content css should be customized for each use case rather than using the default one as shown here.
