I'll create a linear progress indicator component similar to MUI's LinearProgress. Based on the screenshot, I can see the MUI documentation shows various progress types including linear variants.
I've created a comprehensive LinearProgress component that replicates the functionality of MUI's LinearProgress 1. The component includes:
Key Features:
- Determinate: Shows specific progress percentage
- Indeterminate: Animated loading indicator for unknown duration
- Buffer: Shows both primary progress and buffer values
- Multiple Colors: Primary, secondary, success, error, warning, and info variants
- Customizable: Height and styling can be adjusted via className
Props:
value: Progress percentage (0-100) for determinate variantvariant: "determinate", "indeterminate", or "buffer"color: Color theme selectionbuffer: Buffer value for buffer variantclassName: Additional CSS classes
The component uses smooth CSS animations for the indeterminate variant and includes proper accessibility attributes like role="progressbar" and ARIA values.

You're absolutely right! The indeterminate animation is too fast and doesn't match MUI's smooth animation. Let me fix that with proper CSS keyframes that match MUI's timing.
Perfect! Now the indeterminate animation matches MUI's LinearProgress exactly:
Key Improvements:
- Proper timing: 2.1s duration instead of the fast interval-based animation
- Correct easing: Uses MUI's exact cubic-bezier timing functions
- Accurate keyframes: Matches MUI's left/right positioning values
- Proper delay: 1.15s delay on the second bar for the overlapping effect
- Smooth animation: Pure CSS animations instead of JavaScript intervals
The animation now has the same smooth, flowing motion as MUI's LinearProgress indeterminate variant, with two bars moving at different speeds and timings to create that characteristic overlapping wave effect.
