What is Flexbox?

Flexbox allows you to control the layout of items inside a container, making it ideal for building responsive designs. To enable Flexbox, set the container's display property to flex

.flex-container {
  display: flex;
}

Basic Flexbox Properties

1. Flex Direction

The flex-direction property determines the direction of the items inside the flex container. Options are:

• row (default)

• column

    .flex-container {
      display: flex;
      flex-direction: column;
    }
    .flex-item {
      padding: 20px;
      background-color: #add8e6;
      }
  

2. Justify Content

This property controls how items are spaced along the main axis (horizontal by default). Options:

• flex-start, center, space-between, space-around

.flex-container {
  display: flex;
  justify-content: center;
}
.flex-item {
  padding: 20px;
  background-color: #add8e6;
  }

3. Align Items

Aligns items along the cross axis (vertical by default). Options:

• flex-start, center, stretch

.flex-container {
  display: flex;
  align-items: center;
}
.flex-item {
  padding: 20px;
  background-color: #add8e6;
}

4. Flex Wrap

By default, items will stay in one line. To allow items to wrap to the next line:

.flex-container {
  display: flex;
  flex-wrap: wrap;
  margin: 2px;
}
.flex-item {
  padding: 20px;
  background-color: #add8e6;
  }

Example: Simple Flexbox Layout

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

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

.flex-item {
  padding: 50px;
  background-color: lightblue;
}

• Flexbox Layout: The code creates a Flexbox layout with three items inside a flex container.

• display: flex: The container uses display: flex to enable Flexbox, making its child elements behave as flex items.

• justify-content: space-between: This property spaces the items evenly along the horizontal axis, with no space at the start or end.
