Fluid type

Type that scales continuously with the viewport between a floor and a ceiling, instead of stepping at breakpoints.

Near it

clamp(min, preferred, max)	a floor, a rate of change, and a ceiling
the floor	the size below which the type must not go, whatever the viewport does
measured on our own site	15 clamp() expressions, all 15 of them distinct. Floors run 0.9rem to 3.0rem, ceilings 1.6rem to 8.0rem, and a ceiling is between 1.5 and 2.67 times its own floor, median 1.83	measured on ink.css, which is the whole of this site's CSS: one stylesheet, 95 rules, 2 media queries
and the middle term is not always vw	7 in vw, 7 in vh, 1 in cqi	vh scales type to the HEIGHT of the window, which is what a screen meant to be read at arm's length wants and what a scrolling page does not; the one cqi is the single container query on the site
