I am fairly new to the SharePoint Framework development stack and am building a WebPart with AngularJS 1.x and [ngOfficeUIFabric](https://github.com/ngOfficeUIFabric/ng-officeuifabric).

I'm using the current drop (Sharepoint Framework Developer Preview [Drop 6](https://github.com/SharePoint/sp-dev-docs/wiki/Release-Notes-Drop-6): Nov 22, 2016).

Drop 6 comes with an older version of the css files for office ui fabric. I want to update those css files to the current version to be able to use the components.

The proposed solution so far has been to use the ModuleLoader.
First you import ModuleLoader in your code:

    import ModuleLoader from '@microsoft/sp-module-loader';

Then, in the web part's constructor you use it to load the CSS file from CDN:

    public constructor(context: IWebPartContext) {
      super(context);

      ModuleLoader.loadCss('https://appsforoffice.microsoft.com/fabric/2.6.1/fabric.min.css');
      ModuleLoader.loadCss('https://appsforoffice.microsoft.com/fabric/2.6.1/fabric.components.min.css');
    }


**This does not work with Drop 6 anymore.** Apparently there is a problem with webpack:

**How can I reference external css files now?**
