Row

Apply the row patch to any block element to lay out its children as a horizontal flex row with spacing between them, vertically centered by default — the general-purpose primitive for icon+label rows, field rows, and button groups, instead of hand-rolling display: flex; alignItems: center; gap: .... toolbar is a semantic alias of this same shape for headers/nav bars (forwards gap/wrap/justify/align/density).

Props

Prop	Type	Default	Description
`gap`	`number`	`4`	Spacing multiplier for gap between items. With `density: true` (default): `themeSpacing(density × gap)` — at default density (1.5), `gap 4` = `1.5em`. With `density: false`: bare `themeSpacing(gap)` — `gap 4` = `1em`.
`align`	`"flex-start" \| "center" \| "flex-end" \| "stretch" \| "baseline"`	`"center"`	Cross-axis alignment (`alignItems`).
`justify`	`"flex-start" \| "center" \| "flex-end" \| "space-between" \| "space-around" \| "space-evenly"`	unset	Main-axis distribution (`justifyContent`). Left unset by default (flex's own default, `flex-start`).
`wrap`	`boolean`	`false`	Allow items to wrap onto multiple lines (`flexWrap: "wrap"`).
`density`	`boolean`	`true`	When `true`, gap is multiplied by theme density (bounded-control mode). When `false`, gap is structural `themeSpacing(n)` with no density multiply — page/form columns.

Example

import { row } from "@domphy/ui";

const Field = {
  div: [{ label: "Name" }, { input: null, placeholder: "Jane" }],
  $: [row({ justify: "space-between" })],
};

Customization

Must see the source of patch at the bottom of each patch page to understand the structure then code it still code as html native element.

There are four levels of customization, in increasing order of effort:

Patch props. Each patch exposes a small, stable set of props—typically fewer than five. Lowest friction.
Context attributes. Use dataTone, dataSize, and dataDensity on a container to shift tone, size, or density for an entire subtree without touching individual elements.
Inline override. Native-wins merge strategy: any property set directly on the element overrides the patch value.
Create a variant. Clone a similar patch and edit it. Use this only when you need a reusable custom version.

Formulas

Unit - U = fontSize / 4 - convert final values with themeSpacing(n).

Size - n = intrinsic text lines, w = wrapping level, d = density factor:

height        = (n * 6 + 2 * d * w) * U
paddingBlock  = d * w * U
paddingInline = ceil(3 / w) * d * w * U
radius        = d * w * U

Base density d = 1.5:

U	w=0	w=1	w=2	w=3
height (`n = 1`)	6	9	12	15
paddingBlock	0	1.5	3	4.5
paddingInline	3	4.5	6	4.5
radius	0	1.5	3	4.5

Tone - K = N / 2 where N is the palette length. For N = 18, K = 9.

Role	Shift	n=0
Background	parent +/- n	0
Text	bg + K	6
Border	bg + K/2	3
Hover	bg + 2K/3	4
Selected / Focus	above +/- K/3	2-4

State shift range: K/3 <= delta <= 2K/3.

/**
 * A horizontal flex row with spacing between children, vertically centered by

 * and button groups — instead of hand-rolling `display: flex; alignItems:
 * center; gap: ...`. `toolbar()` is a semantic alias of this same shape for
 * headers/nav bars. Styles the host only; apply to any block element.
 *
 * @param props.gap - Spacing multiplier for gap between items (default 4).
 *   Bounded-control mode (`density: true`, default): `themeSpacing(themeDensity(l) * gap)`
 *   — at default density 1.5, gap 4 = 1.5em.
 *   Structural/page-column mode (`density: false`): bare `themeSpacing(gap)` with no
 *   density multiply — gap 4 = 1em, matching AGENTS.md "bare themeSpacing(n)".
 * @param props.align - Cross-axis alignment (`alignItems`). Defaults to `"center"`.
 * @param props.justify - Main-axis distribution (`justifyContent`). Unset by default (flex-start).
 * @param props.wrap - Allow items to wrap onto multiple lines. Defaults to `false`.
 * @param props.density - When true (default), gap is multiplied by theme density
 *   (bounded controls). When false, gap is structural `themeSpacing(n)` — use this
 *   for page/form columns.
 * @example { div: [{ span: "Icon" }, { span: "Label" }], $: [row()] }
 * @example { div: [...], $: [row({ justify: "space-between", wrap: true })] }
 * @example { div: [...], $: [row({ gap: 4, density: false })] }
