🙋 Introduction

The grid-template-columns property in CSS is a fundamental part of the CSS Grid Layout Module. It defines the columns of a grid container, specifying the size and number of columns.

This property allows developers to create complex, responsive layouts with ease.

💡 Syntax

The syntax for the grid-template-columns property involves defining one or more track sizes, which can be a length, a percentage, a fraction, or the keyword auto.

Syntax

Copied

.container {
  grid-template-columns: track-size track-size ...;
}

🎛️ Default Value

The default value of the grid-template-columns property is none, meaning no grid columns are defined, and the grid container has no explicit columns.

🏠 Property Values

Value	Description
length	Defines a fixed size, such as 100px.
percentage	Defines a size relative to the grid container, such as 20%.
auto	Automatically adjusts the column size based on content.
fr	Defines a fraction of the available space, such as 1fr.
minmax(min, max)	Defines a size range, with a minimum and maximum value.
repeat(count, track-size)	Repeats a pattern of columns a specified number of times.

📄 Example

In this example, we'll create a grid with three columns: the first column is 100px wide, the second column is 1fr (taking up the remaining space), and the third column is 200px wide.
