Flexbox is a layout module in CSS that provides a more efficient way to arrange, align and distribute space among items in a container, even when their size is unknown or dynamic.
Flexbox allows you to control the alignment and distribution of elements along a single axis or in multiple dimensions, depending on your needs. It also simplifies many common layout tasks that would otherwise require complex and brittle CSS hacks, such as vertically centering content, creating equal-height columns, and arranging elements in a grid.
Some of the benefits of using flexbox in CSS include:
In this example I’ll align the contents of a card between the available space.
Firstly, I’ll create the structure.
<div class="grid__item">Aligned on the left</div>
<div class="grid__item">Aligned on the right</div>
Then, using CSS, we align the contents in the available space.
display: flex; property activates the flexbox. Then
justify-content: space-between; aligns
.grid__item between the available space. The first one on the left, and the second
.grid__item spaces out to the right.
Flexbox is a powerful tool for creating flexible, responsive layouts that are easy to maintain. The results are also compatible with a wide range of devices and browsers. It’s considered a best practice in CSS because it simplifies many common layout tasks, reduces code complexity, and provides a more efficient use of space.
