🙋 Introduction

The grid-auto-columns property in CSS is used in grid layouts to define the size of implicitly created columns. When items are placed outside the explicitly defined grid, new columns are created automatically.

The grid-auto-columns property specifies the size of these newly created columns, ensuring a consistent layout.

💡 Syntax

The syntax for the grid-auto-columns property is straightforward. You can specify a single value or multiple values separated by spaces.

Syntax

Copied

element {
  grid-auto-columns: value;
}

Here, value can be any valid length, percentage, or keyword that defines the column size.

🎛️ Default Value

The default value of the grid-auto-columns property is auto, which means the size of the implicitly created columns will be determined by the content inside them.

🏠 Property Values

Value	Description
length	A specific size in units such as px, em, rem, etc.
percentage	A percentage value relative to the grid container.
auto	Automatically determines the column size based on the content.
min-content	The smallest size that fits the content.
max-content	The largest size that fits the content.
fit-content()	A function that defines the size within a specified limit.
fr	A fraction of the available space.

📄 Example

In this example, we'll create a grid container where implicitly created columns have a fixed size of 100 pixels.
