CSS Flexbox is a layout module designed to make it easier to align and distribute space between items in a container.

To use Flexbox, you first set the container display to flex.

Example:

.container {
  display: flex;
}

Common Flexbox properties include:

justify-content

Controls horizontal alignment.

justify-content: center;

align-items: center;

Example layout:

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

Flexbox is commonly used for:

• Navigation bars

• Card layouts

• Responsive UI design

• Centering elements

It is one of the most important CSS tools every developer should learn.
