CSS Flexbox Layout Module

Before the Flexbox Layout module, there were four layout modes:

• Block, for sections in a webpage
• Inline, for text
• Table, for two-dimensional table data
• Positioned, for explicit position of an element

The Flexible Box Layout Module, makes it easier to design flexible responsive layout structure without using float or positioning.

Browser Support

The numbers in the table specify the first browser version that fully supports the property.

29.0	11.0	22.0	10	48

Flexbox Elements

To start using the Flexbox model, you need to first define a flex container.

The element above represents a flex container (the blue area) with three flex items.

Example: Create a Flex Container

A flex container with three flex items:

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

You will learn more about flex containers and flex items in the next chapters.
