Fonts
Font sets. Non-serif fonts are most common and hold up well on screens. For larger text like headlines and section titles, a Serif font might be used for contrast.
For websites, fonts might require licensing. Google fonts are free but their designs vary in quality. Adobe fonts are always high quality but they are not free. At the moment, the owner of the website is required to have an Adobe Cloud account in order to use Adobe fonts on the site.
From the Google library, there are some good choices. Open Sans with PT Serif or the Alegreya family with both sans and serif

On a mobile device, all layouts tend to squeeze down to a vertical stream, lessening the difference between the two componsitions.
