Default unit: VMIN
Toucaan defaults to (and strongly recommends) using only the
vmin unit as the single unit of design for all styling needs and element sizing. No other css unit comes close to offering the kind of control and determinism that the viewport minimum unit can.
Block-Scoping Text Size
--fs unit utility variable can be used to assign size to an element just like any other css unit
px, or similar.
width: calc(20 * var(--fs));
height: calc(20 * var(--fs));
font-size: calc(20 * var(--fs) / 5); /* font size is pinned to the width of the element */
Observe the scaling of element and the text within. The size of the text is always pinned to the intrinsic size of the element!
See the CSS is Awesome example with intrinsic scaling.
