Quick reference

Every documented call, beside the CSS it emits.

Call	CSS
`u.divide()`	`css({ "& > *:not(:last-child)": { borderStyle: "solid", borderBlockEndWidth: "1px", borderBlockEndColor: "var(--ui-border, color-mix(in oklab, CanvasText 16%, transparent))" } })`
`u.divide("block", "brand", 2)`	`css({ "& > *:not(:last-child)": { borderStyle: "solid", borderBlockEndWidth: "2px", borderBlockEndColor: "var(--ui-brand-border)" } })`
`u.divide("block", 2)`	`css({ "& > *:not(:last-child)": { borderStyle: "solid", borderBlockEndWidth: "2px", borderBlockEndColor: "var(--ui-border, color-mix(in oklab, CanvasText 16%, transparent))" } })`

Examples

Basic example

Use divide() on a parent to draw a border between each of its children, stacked along the block axis:

Inbox
Drafts
Archive

<ul mix={[divide(), ...]}>
	<li mix={[p(3)]}>Inbox</li>
	<li mix={[p(3)]}>Drafts</li>
	<li mix={[p(3)]}>Archive</li>
</ul>

Dividing a row

Pass "inline" to divide children laid out side by side:

BoldItalicUnderline

<div mix={[hstack(), divide("inline"), ...]}>
	<span mix={[pi(4)]}>Bold</span>
	<span mix={[pi(4)]}>Italic</span>
	<span mix={[pi(4)]}>Underline</span>
</div>

Color and width

Pass a color token and a width in pixels, like divide("block", "brand", 2), or a width alone, like divide("block", 3):

One
Two
Three

One
Two
Three

<div mix={[...]}>
	<ul mix={[divide("block", "brand", 2), ...]}>
		<li mix={[p(3)]}>One</li>
		<li mix={[p(3)]}>Two</li>
		<li mix={[p(3)]}>Three</li>
	</ul>
	<ul mix={[divide("block", 3), ...]}>
		<li mix={[p(3)]}>One</li>
		<li mix={[p(3)]}>Two</li>
		<li mix={[p(3)]}>Three</li>
	</ul>
</div>

Applying on a state

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

u.hover(u.divide())

Responsive design

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

u.at("md", u.divide())

Customizing your theme

Customizing colors

Define a palette as --ui-color-{name}-{50..950} and map a tone onto it with the --ui-{tone}-* variables, the way theme.css maps the built-in ones:

:root {
	--ui-color-info-50: oklch(0.97 0.02 230);
	--ui-color-info-200: oklch(0.88 0.06 230);
	--ui-color-info-500: oklch(0.62 0.16 230);
	--ui-color-info-600: oklch(0.52 0.18 230);
	--ui-color-info-900: oklch(0.3 0.1 230);

	--ui-info-bg-tint: var(--ui-color-info-50);
	--ui-info-bg-solid: var(--ui-color-info-600);
	--ui-info-fg: var(--ui-color-info-600);
	--ui-info-fg-muted: var(--ui-color-info-500);
	--ui-info-fg-emphasis: var(--ui-color-info-900);
	--ui-info-fg-on-solid: white;
	--ui-info-border: var(--ui-color-info-200);
	--ui-info-border-strong: var(--ui-color-info-600);
	--ui-info-ring: var(--ui-color-info-500);
}

declare module "@sdxc/u" {
	interface ColorPalettes {
		info: true;
	}
	interface SemanticTones {
		info: true;
	}
}

The new name is then accepted wherever the scale is:

bg("info")
