Flexbox is a cornerstone of modern web design, providing a powerful, efficient way to layout, align, and distribute space among items in a container. Tailwind CSS takes the complexity out of Flexbox by offering utility classes that let you implement layouts with minimal effort.
What is Flexbox?
Flexbox, short for Flexible Box Layout, is a CSS layout model designed to manage space distribution within a container. It’s particularly useful for:
- Aligning items horizontally or vertically.
- Creating responsive designs without using floats or positioning.
- Dynamically adjusting item sizes based on available space.
Tailwind CSS simplifies Flexbox implementation with intuitive utility classes, allowing developers to achieve complex layouts with minimal custom CSS.
Enabling it’s in Tailwind
To start using Flexbox in Tailwind CSS, you need to define a container as a Flexbox layout. Use the flex
class to enable Flexbox.

<div class="flex">
<div>Item 1</div>
<div>Item 2</div>
<div>Item 3</div>
</div>
Key Concepts
It’s operates on two axes:
- Main Axis: The primary direction items are laid out (horizontal by default).
- Cross Axis: Perpendicular to the main axis.
These axes are controlled in Tailwind using utility classes.
1. Setting the Flex Direction
Flex direction determines how items are placed in the container:
- Row (default): Items are arranged horizontally.
- Column: Items are arranged vertically.
Tailwind provides the following utilities:
flex-row
(default): Horizontal layout.flex-row-reverse
: Reverse horizontal layout.flex-col
: Vertical layout.flex-col-reverse
: Reverse vertical layout
Preview
Show Code
<div class="flex flex-col">
<div>Item 1</div>
<div>Item 2</div>
<div>Item 3</div>
</div>
2. Justifying Content
The justify-content
property aligns items along the main axis. Tailwind offers these utilities:
justify-start
: Align items to the start.justify-center
: Center items.justify-end
: Align items to the end.justify-between
: Space evenly with the first and last items at the container edges.justify-around
: Space evenly with equal padding on both sides of items.justify-evenly
: Equal spacing between items
Preview
Show Code
<div class="flex justify-center">
<div>Item 1</div>
<div>Item 2</div>
<div>Item 3</div>
</div>
3. Aligning Items
The align-items
property controls item alignment along the cross axis. Tailwind provides:
items-start
: Align items to the start.items-center
: Center items.items-end
: Align items to the end.items-baseline
: Align items based on their text baseline.items-stretch
(default): Stretch items to fill the container
Preview
Show Code
<div class="flex items-center">
<div class="h-16 w-16 bg-blue-500">Box 1</div>
<div class="h-24 w-24 bg-red-500">Box 2</div>
<div class="h-20 w-20 bg-green-500">Box 3</div>
</div>
4. Aligning Self
Use align-self
to control the alignment of individual items:
self-auto
(default): Follow the container’salign-items
rule.self-start
: Align the item to the start.self-center
: Center the item.self-end
: Align the item to the end.self-stretch
: Stretch the item.
Preview
Show Code
<div class="flex items-stretch">
<div class="self-start bg-blue-500">Item 1</div>
<div class="self-center bg-red-500">Item 2</div>
<div class="self-end bg-green-500">Item 3</div>
</div>
5. Controlling Flex Wrap
Flexbox allows items to wrap onto multiple lines using the flex-wrap
property. Tailwind utilities include:
flex-nowrap
(default): Prevent wrapping.flex-wrap
: Wrap items onto multiple lines.flex-wrap-reverse
: Wrap items in reverse order
Preview
Show Code
<div class="flex flex-wrap">
<div class="w-1/3 bg-blue-500">Item 1</div>
<div class="w-1/3 bg-red-500">Item 2</div>
<div class="w-1/3 bg-green-500">Item 3</div>
<div class="w-1/3 bg-yellow-500">Item 4</div>
</div>
6. Setting the Order of Items
Use the order
utilities to change the order of items without modifying HTML:
order-{number}
: Assign a custom order.order-first
: Make the item appear first.order-last
: Make the item appear last.order-none
(default): No order changes.
Preview
Show Code
<div class="flex">
<div class="order-2 bg-blue-500">Item 1</div>
<div class="order-1 bg-red-500">Item 2</div>
<div class="order-3 bg-green-500">Item 3</div>
</div>
7. Gap Utilities
Tailwind provides gap
utilities to control spacing between items:
gap-{size}
: Apply a consistent gap.gap-x-{size}
: Horizontal gap.gap-y-{size}
: Vertical gap.
Preview
Show Code
<div class="flex gap-4">
<div class="w-16 h-16 bg-blue-500"></div>
<div class="w-16 h-16 bg-red-500"></div>
<div class="w-16 h-16 bg-green-500"></div>
