Feedback

Alert

A compact message surface for important state without overpowering the page.
Build complete

Generated types are ready.

Live example
import { Alert } from "@hyzrui/core";
 
export function Example() {
  return <Alert title="Build complete">Generated types are ready.</Alert>;
}

Installation

Install the primitive source, then keep editing it inside your app. The command names the component file you want copied.

Command
pnpm dlx hyzrui add alert

Usage

Import the component from the generated source folder and compose it with normal React props.

Import
import { Alert } from "@hyzrui/core";
Usage
<Alert className="my-alert" />

Customization

Every primitive accepts local props and class names, then inherits design tokens from HyzrThemeProvider . Copy the file, keep the markup, and tune the CSS until it matches your product.

Build complete

Generated types are ready.

Radius--hui-radiusControls the default corner system for buttons, inputs, cards, overlays, and nested surfaces.
Foreground--hui-foregroundControls the page and component text colors. Dark mode uses the same component source with different tokens.
Surface--hui-surfaceControls card, dialog, popover, and input surfaces.
Border--hui-borderControls separators, input strokes, card outlines, and menu edges.
Primary--hui-primaryControls the main action color and the matching foreground color for solid controls.
Font--hui-font-familyControls the font stack used by every primitive inside the provider.
Control size--hui-control-font-sizeControls the default font size for buttons, inputs, selects, tabs, command rows, and menu triggers.
Control weight--hui-font-weight-controlControls the default weight of buttons, tabs, menus, badges, and compact actions.
Control height--hui-control-heightControls the default field and trigger height across forms and navigation.
Button height--hui-button-heightControls button height independently from form fields.
Button padding--hui-button-paddingControls horizontal button spacing without changing the text size.
Card padding--hui-card-paddingControls card, dialog, sheet, drawer, and panel interior spacing.
Border width--hui-border-widthControls default edge width for controls, cards, tables, and floating panels.
Focus width--hui-focus-widthControls keyboard focus outline thickness.
Motion duration--hui-transition-durationControls shared hover timing for controls and surfaces.
Hover lift--hui-hover-liftControls subtle hover lift for raised styles.
Overlay--hui-overlayControls dialog, sheet, drawer, and command overlay strength.
Floating offset--hui-floating-offsetControls menu, command, popover, and hover-card distance from the trigger.
Source fileEdit src/lib/hyzrui/components/alert.tsx directly once the primitive is installed in your app.
Local classTarget .hui-alert for local refinements that should not become global theme tokens.
