[ @sdxc/u/size ]

margin-block-end

Applies margin-block-end — the trailing block edge, the bottom edge in a horizontal writing mode.

import { mbe } from "@sdxc/u/size";

Quick reference

Every documented call, beside the CSS it emits.

Call	CSS
`u.mbe(4)`	`css({ marginBlockEnd: "calc(var(--ui-spacing, 0.25rem) * 4)" })`

Use mbe(n) to add margin to the block-end edge of an element, below it in horizontal text:

mbe(8)

<div mix={[...]}>
	<div mix={[mbe(8), ...]}>mbe(8)</div>
</div>

Every scale argument also takes a raw CSS value, which passes through untouched.

u.mbe("2.75rem")

Wrap the call in a state utility to scope it to one selector.

u.hover(u.mbe(4))

Wrap the call in a container query to scope it to one width.

u.at("md", u.mbe(4))

Every numeric step multiplies --ui-spacing, so redefining it rescales every spacing and sizing utility at once:

:root {
	--ui-spacing: 0.25rem;
}

Every call that names the step now reads the new value:

mbe(4)

u.mbe(value: SpacingValue)
