🧱 CSS3 Layout Modules: Flexbox & Grid

CSS3 introduces two powerful layout systems for building flexible, responsive, and scalable web designs.

🔄 Flexbox (One-Dimensional Layout)

Designed for row or column layouts. Simplifies alignment, spacing, and distribution of items within a container.

.display-flex {
  display: flex;
  justify-content: space-between;
  align-items: center;
}

✅ Ideal for:

🔗 Navigation bars
🃏 Card layouts
📱 Responsive menus

🧮 CSS Grid (Two-Dimensional Layout)

Enables complex layouts using rows and columns. Provides precise control over grid structure and item placement.

.grid-container {
  display: grid;
  grid-template-columns: repeat(3, 1fr);
  grid-template-rows: auto;
}

✅ Perfect for:

📰 Magazine-style layouts
🎛️ Dashboard interfaces
🧩 Multi-section responsive pages

🎯 Why Use Both?

📐 Flexbox → Best for linear design patterns
🧱 Grid → Best for structured, grid-based layouts
🔧 Combine both for powerful, maintainable, and adaptive designs

Mastering Flexbox and Grid empowers developers to create modern, responsive, and well-structured web layouts with ease.
