I found a post explaining how “absolutely web-safe fonts do not exist”. Even if that’s the case, I still want to choose a standard font (I decided on it after a green digital skills course I took) .

So I picked a couple of the standard fonts and compared them in a table (see image above). I think I already got a winner. I will apply this change to the site soon together with a few other changes I want to apply to the css files.
