🙋 Introduction

The flex-grow property in CSS is used in flexbox layouts to define the ability of a flex item to grow relative to the rest of the flex items inside the same container.

This property is a crucial part of creating responsive and dynamic layouts, as it allows flex items to expand and fill available space.

💡 Syntax

The syntax for the flex-grow property is simple and involves specifying a positive number, which represents the proportion of available space the item should take up relative to other flex items.

Syntax

Copied

element {
  flex-grow: number;
}

Here, number is a unitless value that determines how much of the available space inside the flex container the item should take up.

🎛️ Default Value

The default value of the flex-grow property is 0, which means the flex item will not grow and will only take up the space it needs based on its content.

🏠 Property Values

Value	Description
number	A unitless value that represents the flex grow factor. A value of 0 means the item will not grow. Positive integers specify how much the item will grow relative to the other flex items.

📄 Example

In this example, we'll create a flex container with three items. The second item will be set to grow twice as much as the first item, while the third item will not grow.
