.Net Core 2 SPA/Angular Template - Render Global CSS

Question

I am very new to Webpack and the .NET Core 2 Angular SPA Template. I'm trying to create a global stylesheet for the entire site. I could reference that style in the Layout view to render it in the main view, but then I lose the benefits of the pre-render engine and bundling with WebPack (as well as minification).

The Webpack documentation says that in order to include static CSS that you need to add a require(../filepath) to your module, but I don't see a way to do this in the boot.browser.ts.

I'm still just getting started with .NET core so my site is basically just the OOB .Net Core 2 template with Angular. I'm keeping my global styles sheet in ClientApp/Styles/Global.css at the moment. Thanks for your time.
