What is Flexbox

Flexbox, short for flexible box, is a layout mode in CSS that makes it easy to create flexible and responsive layouts. It consists of two main components:

• flex containers and
• flex items It's perfect for building navigation bars, footers, and other components that need to adapt to different screen sizes.

How to Use Tailwind CSS Flex

Using Tailwind CSS flex is incredibly easy. Here are the basic classes you need to get started:

• flex - enables flexbox layout
• flex-wrap - wraps flex items to a new line
• justify-center - centers flex items horizontally
• justify-space-between - distributes flex items evenly
• items-center - centers flex items vertically
• self-center - centers a single flex item

Key Tailwind CSS Flex Utilities

Here’s a breakdown of the most commonly used Tailwind CSS Flex utilities:

Flex Containers

A flex container holds multiple flex items and defines the main axis and cross axis of the flex layout. To create a Tailwind flex container, simply apply the flex class to an element. By default, the flex-direction property is set to row, which means the flex items will be arranged horizontally.

Here's an example of creating a flex container:

<div class="flex">
	<!-- Flex items go here -->
</div>

Flex Items

Flex items are the individual elements within a flex container. They can be manipulated and positioned within the container using flex utilities. By default, flex items will be arranged in the order they appear in the HTML markup.

Here's an example of creating flex items within a flex container:

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

Modifying Flex Direction

The flex-direction utility allows you to specify the direction in which flex items are arranged within the flex container. By default, the direction is set to row, which arranges the items horizontally. However, you can easily change it to column to arrange the items vertically.

Tailwind flex row

You can use the Tailwind flex row class to position flex items horizontally in the same direction as the text. It is one of the classes of Tailwind flex-direction utilities.

<div class="flex flex-row ...">
	<div class="flex items-center justify-center bg-indigo-500...">A</div>
	<div class="flex items-center justify-center bg-indigo-500...">B</div>
	<div class="flex items-center justify-center bg-indigo-500...">C</div>
</div>

The code above represents the flex-row class

Tailwind Flex row reverse

This Tailwind flex row reverses class positions the flex item horizontally in the opposite direction of the text:

<div class="flex flex-row-reverse.....">
    <div class="flex items-center justify-center bg-indigo-500...">
      1
    </div>
    <div class="flex items-center justify-center bg-indigo-500...">
      2
    </div>
    <div class="flex items-center justify-center bg-indigo-500...">
      3
    </div>
    <div class="flex items-center justify-center bg-indigo-500...">
      4
    </div>
  </div>
</div>

Tailwind Flex column

The tailwind flex column is one of the flex-direction classes and its function is to position items vertically on the screen. You can see an example of the code below and its resulting image.

      A
    </div>
    <div class="flex items-center justify-center bg-indigo-500...">

      C
    </div>
  </div>

Tailwind Flex Column Reverse

<div class="flex flex-col-reverse...">
	<div class="flex items-center justify-center bg-indigo-500...">A</div>
	<div class="flex items-center justify-center bg-indigo-500...">B</div>

Controlling Flex Item Alignment

Tailwind CSS provides utilities to control the alignment of flex items along both the main axis and the cross axis. The justify-* utilities control the alignment along the main axis, while the items-* utilities control the alignment along the cross axis.

• Justify Content
• Align Items
• Align Self

Justify Content

The justify-* utilities control how flex items are distributed along the main axis (horizontal axis by default). Here are some of the Utilities avaliable with this class.

• justify-start: Aligns items to the start (default).

• justify-end: Aligns items to the end.

• justify-center: Centers items.

• justify-between: Distributes items evenly, with the first item at the start and the last at the end.

• justify-around: Distributes items evenly with equal space around them.

• justify-evenly: Distributes items evenly with equal space between and around them.

<div class="flex flex-row justify-evenly....">
		<div class="bg-indigo-500 text-white...">A</div>
		<div class="bg-indigo-500 text-white...">B</div>
		<div class="bg-indigo-500 text-white...">C</div>
	</div>

• items-start: Aligns items to the start.

• items-end: Aligns items to the end.

• items-center: Centers items vertically.

• items-baseline: Aligns items to their baselines.

Adjusting Flex Item Sizing

You can adjust the sizing of flex items using utilities such as flex-grow, flex-shrink, and flex-auto. These utilities allow you to control how flex items grow, shrink, or automatically adjust their size to fill the available space. These are the classes.

• Tailwind Flex Auto
• Tailwind Flex Grow
• Tailwind Flex Shrink

Tailwind Flex-Auto

The Tailwind flex-auto class shows how much an item will grow relative to the content of the flexible items. Here, the initial size is ignored, and it grows and shrinks according to its need.

<div class="flex...">
	<div class="flex-none...">A</div>
	<div class="flex-auto...">B</div>
	<div class="flex-auto...">C</div>
</div>

In the code above, we demonstrated how to use the flex-auto class in Tailwind CSS.

Preview

Tailwind Flex Grow

The flex-grow utility controls the ability of a flex item to grow and take up additional space if available. By default, it is set to 0, meaning the flex item will not grow. You can adjust the value to control the growability of a flex item.

<div class="flex...">
	<div class="flex-none... ">A</div>
	<div class="flex-grow...">B</div>
	<div class="flex-none...">C</div>
</div>

Tailwind Flex Shrink

The flex-shrink utility controls the ability of a flex item to shrink if necessary. By default, it is set to 1, meaning the flex item can shrink to fit the available space.

<div class="flex...">
	<div class="flex...">A</div>
	<div class="flex-shrink...">B</div>
	<div class="flex...">C</div>
</div>

The code above shows flex-shrink class.

Wrapping Flex Items

By default, flex items will try to fit in a single line within the flex container. However, you can enable wrapping using the flex-wrap utility. These are the classes used to achieve this

• Tailwind Flex Wrap
• Tailwind Flex Wrap-reverse
• Tailwind Flex No-Wrap

Tailwind Flex Wrap

Tailwind Flex Wrap class makes it possible for flex items to wrap onto multiple lines if needed, instead of being forced into a single line.

Here's an example of wrapping flex items:

<div
    class="flex flex-wrap..."
  >
    <div class="flex...">
      A
    </div>
    <div class="flex...">
      B
    </div>
    <div class="flex...">
      C
    </div>
  </div>
</div>

Flex wrap reverse is a utility class that reverses the wrap flex items.

<div
    class="flex flex-wrap-reverse..."
  >
    <div class="flex...">
      A
    </div>
    <div class="flex...">
      B
    </div>
    <div class="flex...">
      C
    </div>
  </div>
</div>

The code above represents the flex-wrap-reverse class.

Preview

Tailwind CSS Flex-no-wrap

This Tailwind class doesn't allow flex items to wrap. This makes these flex items overflow the container. It doesn't regulate flex items to a box.

<div class="flex flex-nowrap...">
	<div class="flex...">A</div>
	<div class="flex...">B</div>
	<div class="flex...">C</div>
</div>
