Choosing The Right Font For Your Site
In traditional typography, a font is a particular size, weight and style of a typeface. Each font was a matched set of metal type, one piece (called a “sort”) for each glyph, and a typeface comprised a range of fonts that shared an overall design.
In modern usage, with the advent of digital typography, font is frequently synonymous with typeface. In particular, the use of “vector” or “outline” fonts means that different sizes of a typeface can be dynamically generated from one design.
