Progress

🎯 Bootstrap Progress Bars: Your Visual Journey Tracker!

The Story of the Loading Bar

Imagine you’re downloading your favorite game. You see a bar slowly filling up from empty to full. That bar tells you: “Hey, we’re working on it! Almost there!”

That’s exactly what a Progress Bar does! It’s like a thermometer for tasks — showing how much is done and how much is left.

Bootstrap makes creating these progress bars super easy. Let’s explore every flavor together!

🌟 Chapter 1: The Basic Progress Bar

Think of this as your plain vanilla ice cream — simple, classic, and works everywhere!

How It Works

A Bootstrap progress bar has two parts:

1. The Container (.progress) — The empty track
2. The Fill (.progress-bar) — The colored part that grows

<div class="progress">
  <div class="progress-bar"
       style="width: 50%">
  </div>
</div>

This shows a bar half filled (50%). Easy, right?

    B --> C["Width Controls %"]
    C --> D["Visual Feedback!"]

The Magic

• The outer div creates the gray track
• The inner div with .progress-bar creates the blue fill
• Change the width to show different amounts!

📝 Chapter 2: Progress Labels

What if the bar could talk? That’s what labels do!

Instead of just showing color, we add text inside the bar to say exactly what percentage we’re at.

<div class="progress">
  <div class="progress-bar"
       style="width: 75%">
    75%
  </div>
</div>

Now users see “75%” right inside the bar!

Pro Tips for Labels

📏 Chapter 3: Progress Height

Want a thicker or thinner bar? Bootstrap lets you control the height!

Thin Bar (Sleek Look)

<div class="progress"
     style="height: 5px">
  <div class="progress-bar"
       style="width: 40%">
  </div>
</div>

Thick Bar (Bold Look)

<div class="progress"
     style="height: 25px">
  <div class="progress-bar"
       style="width: 60%">
    60%
  </div>
</div>

When to Use What?

🎨 Chapter 4: Progress Backgrounds

Why stay blue when you can have ANY color?

Bootstrap offers semantic colors — colors that mean something!

<!-- Success: Green = Good! -->
<div class="progress">
  <div class="progress-bar bg-success"
       style="width: 100%">
  </div>
</div>

<!-- Warning: Yellow = Caution -->
<div class="progress">
  <div class="progress-bar bg-warning"
       style="width: 50%">
  </div>
</div>

<!-- Danger: Red = Alert! -->
<div class="progress">
  <div class="progress-bar bg-danger"
       style="width: 25%">
  </div>
</div>

<!-- Info: Light Blue = Info -->
<div class="progress">
  <div class="progress-bar bg-info"
       style="width: 75%">
  </div>
</div>

🧩 Chapter 5: Multiple Bars (Stacked Progress)

What if you want to show multiple things in one bar?

Like a battery showing:

• 🟢 Used by apps
• 🔵 Used by system
• ⚪ Free space

<div class="progress">
  <div class="progress-bar bg-success"
       style="width: 35%">
    Apps
  </div>
  <div class="progress-bar bg-info"
       style="width: 20%">
    System
  </div>
  <div class="progress-bar bg-warning"
       style="width: 15%">
    Other
  </div>
</div>

All three bars sit side by side inside one container!

    A["35% Green"] --> B["20% Blue"]
    B --> C["15% Yellow"]
    C --> D["30% Empty"]

Rules for Multiple Bars

1. All percentages should add up to ≤ 100%
2. Each bar gets its own color
3. They stack left to right

🦓 Chapter 6: Striped Progress

Want your bar to look fancy? Add stripes!

Stripes make your progress bar look like a candy cane or barber pole.

<div class="progress">
  <div class="progress-bar
              progress-bar-striped"
       style="width: 50%">
  </div>
</div>

Striped + Colors

<!-- Striped Success -->
<div class="progress">
  <div class="progress-bar
              progress-bar-striped
              bg-success"
       style="width: 70%">
  </div>
</div>

<!-- Striped Danger -->
<div class="progress">
  <div class="progress-bar
              progress-bar-striped
              bg-danger"
       style="width: 30%">
  </div>
</div>

The stripes are diagonal lines that add visual interest!

🎬 Chapter 7: Animated Progress

The ultimate progress bar — stripes that MOVE!

This creates a “loading” effect where the stripes flow continuously.

<div class="progress">
  <div class="progress-bar
              progress-bar-striped
              progress-bar-animated"
       style="width: 75%">
  </div>
</div>
