CSS Flexbox is a layout module that provides a flexible way to arrange items within a container. It's ideal for creating responsive and adaptable designs.

Core Concepts 🔧

  • Flex Container: The parent element that enables Flexbox properties. Example: .container { display: flex; }
  • Flex Items: Child elements within the container. They automatically adjust to fit the space.
  • Direction: Control layout direction with flex-direction (e.g., row, column, row-reverse, column-reverse)
  • Alignment: Use justify-content and align-items for spacing and alignment (e.g., space-between, center, flex-start)

Use Cases 📱

  • Responsive navigation menus
  • Card layouts with dynamic spacing
  • Form elements alignment
  • Equal height columns

Example Code 💻

.container {
  display: flex;
  flex-wrap: wrap;
  gap: 1rem;
}

.item {
  flex: 1 1 200px;
  background: #f0f0f0;
  padding: 1rem;
}

Common Issues ⚠️

  • Overlapping elements: Use flex-wrap: wrap or flex-wrap: nowrap
  • Uneven spacing: Adjust gap or justify-content
  • Alignment problems: Check align-items and align-content
