There are over 10,000 typefaces available for computers. The general categories are: oldstyle (faces have slanted serifs, gradual thick to thin strokes and a slanted stress – the “O” appears slanted), modern (faces have thin, horizontal serifs, radical thick to thin strokes and a vertical street – the “O” does not appear to slant); slab serif (faces have thick, horizontal serifs, little or no thick-to-thin in the strokes and a vertical stress – the “O” appears vertical); sans serif (faces have no serifs), script (from elaborate handwriting styles to casual, freeform, unconnected letter forms), decorative unusual fonts (designed to be very different and attention getting)..”
