### Basic Horizontal Progress

Simple horizontal progress tracker:

```jsx
import ProgressTracker from '@aniruddha1806/progress-tracker';

function BasicExample() {
  const steps = [
    { label: 'Start', icon: '🚀' },
    { label: 'Progress', icon: '⚡' },
    { label: 'Complete', icon: '🎉' }
  ];

  return (
    <ProgressTracker
      steps={steps}
      currentStep={1}
    />
  );
}
```


### Custom Colors and Styling

Customize appearance with colors and CSS classes:

```jsx
import ProgressTracker from '@aniruddha1806/progress-tracker';
import './custom-progress.css'; // Your custom CSS

function CustomStyledExample() {
  const steps = [
    { label: 'Design', icon: '🎨' },
    { label: 'Develop', icon: '💻' },
    { label: 'Test', icon: '🧪' },
    { label: 'Deploy', icon: '🚀' }
  ];

  return (
    <ProgressTracker
      steps={steps}
      currentStep={2}
      activeColor="#28a745"
      inactiveColor="#f8f9fa"
      size="large"
      connectorStyle="dashed"
      className="custom-progress"
      stepClassName="custom-step"
      labelClassName="custom-label"
    />
  );
}
```

CSS file (custom-progress.css):
```css
.custom-progress {
  background: linear-gradient(135deg, #667eea 0%, #764ba2 100%);
  border-radius: 12px;
  padding: 24px;
}

.custom-step {
  transition: transform 0.2s ease;
}

.custom-step:hover {
  transform: scale(1.05);
}

.custom-label {
  font-family: 'Inter', sans-serif;
  font-weight: 600;
  color: white;
}
```

## TypeScript Usage

The component provides full TypeScript support:

```typescript
import ProgressTracker, { Step, ProgressTrackerProps } from '@aniruddha1806/progress-tracker';
import { ReactNode } from 'react';

interface CustomStep extends Step {
  id: string;
  duration?: number;
  isOptional?: boolean;
}

interface WizardProps {
  steps: CustomStep[];
  onStepChange: (stepIndex: number) => void;
}

const CustomWizard: React.FC<WizardProps> = ({ steps, onStepChange }) => {
  const [currentStep, setCurrentStep] = useState<number>(0);

  const handleStepClick = (stepIndex: number): void => {
    setCurrentStep(stepIndex);
    onStepChange(stepIndex);
  };

  const renderCustomStep = (
    step: Step, 
    index: number, 
    isCompleted: boolean, 
    isActive: boolean
  ): ReactNode => {
    const customStep = step as CustomStep;
    
    return (
      <div
        key={customStep.id}
        onClick={() => handleStepClick(index)}
        style={{
          cursor: 'pointer',
          opacity: customStep.isOptional && !isCompleted ? 0.6 : 1
        }}
      >
        {/* Custom step rendering */}
      </div>
    );
  };

  const progressProps: ProgressTrackerProps = {
    steps,
    currentStep,
    renderCustomStep,
    activeColor: '#6366f1',
    size: 'large'
  };

  return <ProgressTracker {...progressProps} />;
};
```
