Quick reference

Every documented call, beside the CSS it emits.

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

Examples

Basic example

Use insIs(n) to set the inset-inline-start offset of a positioned element from the spacing scale, the left edge in left-to-right text:

insIs(0)

insIs(6)

<div mix={[...]}>
	<div mix={[relative(), is(48), bs(32), ...]}>
		<div mix={[absolute(), insIs(0), ...]}>insIs(0)</div>
	</div>
	<div mix={[relative(), is(48), bs(32), ...]}>
		<div mix={[absolute(), insIs(6), ...]}>insIs(6)</div>
	</div>
</div>

Right-to-left support

The offset follows the writing direction, so insIs(4) holds to the left in ltr text and to the right in rtl text:

ltr

rtl

<div mix={[...]}>
	<div dir="ltr" mix={[relative(), is(48), bs(32), ...]}>
		<div mix={[absolute(), insIs(4), ...]}>ltr</div>
	</div>
	<div dir="rtl" mix={[relative(), is(48), bs(32), ...]}>
		<div mix={[absolute(), insIs(4), ...]}>rtl</div>
	</div>
</div>

Using a custom value

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

u.insIs("2.75rem")

Applying on a state

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

u.hover(u.insIs(4))

Responsive design

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

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

Customizing your theme

Customizing spacing

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:

insIs(4)

Signature

u.insIs(value: SpacingValue)
