🔹 What is CSS Flexbox?

Flexbox is a one-dimensional layout system.

Flexbox is best for components, not full page layouts.

.flex {
  display: flex;
}
Item 1
Item 2
Item 3

Example 2: Center Items (Most Common Use Case)

.flex {
  display: flex;
  justify-content: center;
  align-items: center;
}
Centered

Example 3: Space Between Items

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