This month I have selected two serif fonts, Cinzel Decorative (www.fontsquirrel.com/fonts/cinzel), the headings and Forum (www.fontsquirrel.com/fonts/forum), the text. You can see them here in Shoehorn for M3.0 alongside its syntax highlighting feature:

I'm not normally a fan of serif fonts. However, after watching the business news it struck me that a business orientated learning environment might wish to present itself in a formal way.
Why two fonts? Well I tried Cinzel (Decorative) on its own for both the headings and the text but discovered at smaller sizes the font was not so readable. Thus going on to choose Forum for the text as a suitable complimentary font.
