Comparing Flexbox and Grid for Efficient Two-Column Layouts

Introduction
Ever wondered whether to use Flexbox or Grid for a simple two-column layout?
You’re not alone. Both are powerful — but they shine in different situations.
In this article, we’ll break down both approaches with beginner-friendly code, visuals, and practical tips to help you choose wisely.
Section 1: Flexbox in Action
What It Is:
Flexbox is like a row of containers that adjust themselves automatically. Great for content that flows in one direction — either row or column.
When to Use It:
Perfect for one-dimensional layouts, like:
A navbar
A row of cards
A two-column layout with flexible content
Flexbox Two-Column Layout Example:
<div class="flex-container">
<div class="left-column">Left Side</div>
<div class="right-column">Right Side</div>
</div>
.flex-container {
display: flex;
}
.left-column {
flex: 1; /* Takes up 50% */
padding: 10px;
}
.right-column {
flex: 1;
padding: 10px;
}
What’s Happening:
display: flex
arranges children side-by-side.flex: 1
gives both columns equal width.Padding gives breathing space.
Section 2: Grid in Action
What It Is :
Grid is like an Excel sheet. It gives you a full grid system (rows and columns). Great for complex, two-dimensional layouts.
When to Use It:
Ideal for:
Dashboards
Webpage layouts
Multi-column or row structures
Grid Two-Column Layout Example:
<div class="grid-container"> <div class="left-column">Left Side</div> <div class="right-column">Right Side</div> </div>
.grid-container { display: grid; grid-template-columns: 1fr 1fr; gap: 20px; }
What’s Happening:
grid-template-columns: 1fr 1fr
creates two equal-width columns.
gap
adds spacing between them.
