Text blocks should be constructed such that they 'honor and reveal' the relationships between the various elements – headings, subheadings, quotes, asides and footnotes. Robert Bringhurst recommends a character count per line of approximately 66 letters for optimum legibility, but accepts that anything between 45 and 75 is satisfactory. This has implications with regard to min-width and max-width settings on text containers, particularly in relation to responsive frameworks, such as Foundation, Columnal and Skeleton.
