Hi,
I am using the Artful theme and I try to realise the local hosting of Google WebFonts.
I started with the font Oswald, uploaded the font to my server and changed the css. Hopefully I have done everything right - I did it for the first time.
I see 1) a local overwrite message, and 2) further down a css file on https://fonts.googleapis.com and 3) When I look at the page source code, I can still see in the header links to Google Fonts:
A check of my webpage tells me that there are third-party requests all about the WebFonts.
Now I wonder whether the local hosting really works? Or in other words: can I delete these links completely
<link href="https://fonts.googleapis.com/css?family=Oswald:400" rel="stylesheet" media="all"
in the header and if yes - how?
I would be very grateful for your support! 
Kind regards,
Katharina
