Introduction

Flexbox and Grid are the two most powerful layout systems in CSS.
But beginners often get confused about when to use which.
Diffcozen explains the differences clearly.

What Is Flexbox?

Flexbox is a one-dimensional layout system.
It is perfect for arranging items in a row or column.

Best for:

• Navbars
• Button groups
• Horizontal layouts
• Vertical centering

What Is CSS Grid?

Grid is a two-dimensional layout system.
It is ideal for complex structures.

Best for:

• Dashboards
• Image galleries
• Multi-column layouts
• Responsive sections

When to Use Flexbox?

Use Flexbox when:

• You want items aligned in one direction
• You need equal spacing
• You want auto-adjusting layouts

When to Use Grid?

Use Grid when:

• Layout needs rows + columns
• Areas need to be defined
• You want complex responsive design

Example Comparison

Flexbox:

.container {
  display: flex;
  gap: 20px;
}

Grid:

.container {
  display: grid;
  grid-template-columns: repeat(3, 1fr);
  gap: 20px;
}
