autofill

Overrides the browser's autofill background and text color under &:-webkit-autofill, so an autofilled input keeps the appearance every other input has.

Quick reference

Every documented call, beside the CSS it emits.

Call	CSS
`u.autofill()`	`css({ "&:-webkit-autofill": { boxShadow: "0 0 0 1000px var(--ui-bg, Canvas) inset !important", WebkitBoxShadow: "0 0 0 1000px var(--ui-bg, Canvas) inset !important", WebkitTextFillColor: "var(--ui-fg, CanvasText) !important" } })`

Examples

Basic example

Use autofill() to keep an autofilled field on the page's own background and text color. Let the browser fill the field to see it:

<form mix={[...]}>
	<input
		type="email"
		name="email"
		autocomplete="email"
		placeholder="you@example.com"
		mix={[autofill(), ...]}
	/>
</form>

Custom colors

Pass a background and a text color, like brand.tint and brand.emphasis, for a field that lives on a tinted surface:

<form mix={[surface("brand.tinted"), rounded("lg"), p(4)]}>
	<input
		type="text"
		name="name"
		autocomplete="name"
		placeholder="Full name"
		mix={[autofill("brand.tint", "brand.emphasis"), ...]}
	/>
</form>

u.autofill("neutral.tint", "neutral")

Applying on a state

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

u.hover(u.autofill())

Responsive design

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

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

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:

autofill("info")
