Mastering the Flexbox in CSS: A Comprehensive Guide


If you've been in the web development industry, you've probably heard about Flexbox1. Flexbox, or the Flexible Box Layout, is a powerful tool in CSS that makes it easier than ever to design flexible, responsive layouts. Before Flexbox, there were four layout modes: block, inline, table, and positioned2. However, Flexbox has brought about a more efficient way to layout, align, and distribute space among items in a container even when their sizes are unknown or dynamic.

Understanding the Basic Concepts of Flexbox

The Flex Container

In Flexbox, the parent element becomes a flex container3. This container can alter its items' width and height to best fill the space available, making it a popular choice for responsive designs1. The items within a flex container are called "flex items."3

The Axes of Flexbox

A critical concept in flexbox is the idea of axes. By default, flex items are laid out along the horizontal axis, from left to right3. This is known as the main axis. The vertical axis, running perpendicular to the main axis, is called the cross axis3.

Start and End Lines

The starting edge of the main axis is the "main start," and the ending edge is the "main end." Similarly, for the cross-axis, the beginning is the "cross start" and the ending edge is the "cross end."3 This nomenclature is important, especially when aligning items within the flex container.

Making the Most Out of Flexbox

Flex-Wrap Property

Flexbox brings along the flex-wrap property, allowing you to control if the items should wrap onto multiple lines3. By default, flex items will all try to fit onto one line, but with flex-wrap you can change this behavior.

The Flex-flow Shorthand

The flex-flow property is a shorthand property for setting both the flex-direction and flex-wrap properties3. The first value specifies the flex direction, and the second value specifies whether the flex items should wrap.
