CSS Grid vs Flexbox: When to Use Which

Introduction

CSS Grid and Flexbox are powerful layout techniques, but each serves different purposes. Understanding when to use them improves efficiency and design consistency.

1. Overview of CSS Grid

CSS Grid is a two-dimensional layout system, allowing precise control over rows and columns.

Basic Grid Structure

.container {
    display: grid;
    grid-template-columns: repeat(3, 1fr);
    grid-template-rows: auto;
    gap: 10px;
}

Creates a 3-column layout with equal width.

Grid Item Placement

.item {
    grid-column: 1 / span 2;
}

Spans two columns.

2. Overview of Flexbox

Flexbox is a one-dimensional layout system, ideal for aligning items in rows or columns.

Basic Flexbox Structure

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

Aligns items horizontally with equal spacing.

Flex Direction

.container {
    flex-direction: column;
}

Stacks items vertically.

3. When to Use Grid vs Flexbox

Use Grid When:

• You need a complex multi-row/column layout.

Use Flexbox When:

Conclusion

Both CSS Grid and Flexbox have their strengths. Grid is best for structured layouts, while Flexbox excels in flexible alignments.
