Can I link to external CSS?

Question

I know I can add CSS into a custom and footer, but is there a way to add an external reference to another CSS file for the entire hub site? Specifically I'd like to use.... rel="stylesheet" href="path/to/font-awesome/css/font-awesome.min.css"> It could be handy if I could just point at my organizations existing CSS (although I do realize this creates possible conflicts and I'm not sure how they would be resolved) Sort of related to this - it seems I can only set the font to a provider from an external URL. Is there a way I can override the font with one that "all computers have installed", like Sans-Serif or Times New Roman. The website I'm working on uses the following font definition: Helvetica,Arial,"Roboto",sans-serif;

Thanks Klara. I asked in the wrong section. I was hoping to do this in an Experience Builder app hosted on ArcGIS.com but don't see that option any longer. It seems to only be allowed on self-hosted Experience Builder apps. Thanks for showing how to do it in a Hub though for others to see!

You can add fonts to the Hub site theme by going to the site editor, then selecting theme, and then scrolling down past the list of colors where we have two fields for setting base font and heading font. Select the gear icon and this will launch a model where you can add your Google fonts.

How do we use Google fonts if we can't do so by using <link rel="stylesheet"
href="https://fonts.googleapis.com/css?family=Source Sans Pro"> ?
