Introduction
Creating responsive layouts used to be a hassle, but CSS Flexbox changed everything. If you're looking for a simple, powerful way to build dynamic web layouts, Flexbox is your best friend.

🔍 What Is Flexbox?

Flexbox (Flexible Box Layout) is a CSS layout model that allows items within a container to be automatically arranged depending on screen size and content. It’s perfect for both 1D layouts (rows or columns), making it ideal for mobile-first design.

📐 Key Flexbox Properties

Property	Description
`display: flex`	Turns an element into a flex container.
`flex-direction`	Defines the direction (row, column, etc.).
`justify-content`	Aligns items along the main axis.
`align-items`	Aligns items along the cross axis.
`flex-wrap`	Allows items to wrap onto multiple lines.
`flex`	Controls the size of flex items.

🧪 Example: Basic Flex Layout

<div class="flex-container">
  <div>Item 1</div>
  <div>Item 2</div>
  <div>Item 3</div>
</div>

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

This creates a row of three items, spaced evenly.
