ProgressBar
A progress bar shows either determinate or indeterminate progress of an operation over time.
Completeness: styles-sufficient
The stylesheet is the whole component. There is no keyboard map beyond what the native element already does and nothing sets state at runtime that the CSS keys on, so a CSS-only port reproduces it.

Use isIndeterminate when progress cannot be determined.
import {Label, ProgressBar} from "@blakeui/react";
export function Indeterminate() {
return (
<ProgressBar isIndeterminate aria-label="Loading" className="w-64">Custom Value Scale
Use minValue, maxValue, and formatOptions to customize the value range and display format.
"use client";
import {Label, ListBox, NumberField, ProgressBar, Select, Separator} from "@blakeui/react";
import {useState} from "react";
Without Label
When no visible label is needed, use aria-label for accessibility.
import {ProgressBar} from "@blakeui/react";
export function WithoutLabel() {
return (
<ProgressBar aria-label="Loading progress" className="w-64" value={45}>Styling
Passing Tailwind CSS classes
You can customize individual ProgressBar parts:
import { ProgressBar, Label } from '@blakeui/react';
function CustomProgressBar() {
return (
<ProgressBar value={60}>
<Label>Loading</Label>
<ProgressBar.Output />
<ProgressBar.Track className="bg-purple-100 dark:bg-purple-900">
<ProgressBar.Fill className="bg-purple-500" />
</ProgressBar.Track>
</ProgressBar>
);
}Customizing the component classes
To customize the ProgressBar component classes, you can use the @layer components directive.

A worked example is in Styling.
blakeUI follows the BEM methodology to ensure component variants and states are reusable and easy to customize.
