@pd
Pick the arguments in a shuffled order, one per cell. Every value is used once before the order repeats, so a set of 4 values covers 4 cells without duplicates.
Syntax
- @pd(<value>, ...)
- @pd([<range>])
The shuffle is done once per call site, so a 25-cell grid and @pd with 25 values
is a random permutation of them. After a full round the same shuffled order repeats.
The shuffle depends on the seed.
@pick-d is an older name.
The uppercase @PD reads the enclosing sequence step instead.
Examples
@grid: 5 / 60vmin _1px;
background: @pd(#000, #e6437d, #ebbf4d, #fff);A random permutation of positions, each used exactly once:
@grid: 5 / 60vmin;
@size: 19%;
@content: @i;
background: #000;
color: #fff;
@place: @pd.m5x5(
@nx(*20%, -10%) @ny(*20%, -10%)
);
