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.
Well, the clock says it's time to close now
I guess I'd better go now
I'd really like to stay here all night
The cars crawl past all stuffed with eyes
Street lights share their hollow glow
Your brain seems bruised with numb surprise
Still one place to go
Still one place to go
Let me sleep all night in your soul kitchen
Warm my mind near your gentle stove
Turn me out and I'll wander baby
Stumblin' in the neon groves
Well, your fingers weave quick minarets
Speak in secret alphabets
I light another cigarette
Learn to forget, learn to forget
Learn to forget, learn to forget
Let me sleep all night in your soul kitchen
Warm my mind near your gentle stove
Turn me out and I'll wander baby
Stumblin' in the neon groves
Well the clock says it's time to close now
I know I have to go now
I really want to stay here
All night, all night, all night
