Anvil2 uses partial increments of a base-`0.5rem` spacing scale. Quarter and half values of `0.0625rem` and `0.125rem` are also included.

## CSS Utilities

Anvil provides size utility variables for common spacing needs.

export const spacingUtilities = [{
  scssVar: "$size-0",
  cssVar: "--size-0",
  value: "0rem",
  valuePx: "0px"
}, {
  scssVar: "$size-quarter",
  cssVar: "--size-quarter",
  value: "0.0625rem",
  valuePx: "1px"
}, {
  scssVar: "$size-half",
  cssVar: "--size-half",
  value: "0.125rem",
  valuePx: "2px"
}, {
  scssVar: "$size-1",
  cssVar: "--size-1",
  value: "0.25rem",
  valuePx: "4px"
