Default behavior

Short
Medium length
Significantly larger amount of content

With .flex-1

Short

<div class="flex bg-gray-200">
  <div class="flex-1 text-gray-700 text-center bg-gray-400 px-4 py-2 m-2">

  </div>
  <div class="flex-1 text-gray-700 text-center bg-gray-400 px-4 py-2 m-2">

  <div class="flex-1 text-gray-700 text-center bg-gray-400 px-4 py-2 m-2">
    Significantly larger amount of content
  </div>
</div>

Auto

Use .flex-auto to allow a flex item to grow and shrink, taking into account its initial size:

Default behavior

Short
Medium length
Significantly larger amount of content

With .flex-auto

Short
Medium length
Significantly larger amount of content
<div class="flex bg-gray-200">
  <div class="flex-auto text-gray-700 text-center bg-gray-400 px-4 py-2 m-2">

  </div>
  <div class="flex-auto text-gray-700 text-center bg-gray-400 px-4 py-2 m-2">

  <div class="flex-auto text-gray-700 text-center bg-gray-400 px-4 py-2 m-2">
    Significantly larger amount of content
  </div>
</div>

None

Use .flex-none to prevent a flex item from growing or shrinking:

Item that can grow or shrink if needed
Item that cannot grow or shrink
Item that can grow or shrink if needed
<div class="flex bg-gray-200">
  <div class="flex-1 text-gray-700 text-center bg-gray-400 px-4 py-2 m-2">
    Item that can grow or shrink if needed
  </div>
  <div class="flex-none text-gray-800 text-center bg-gray-500 px-4 py-2 m-2">
    Item that cannot grow or shrink
  </div>
  <div class="flex-1 text-gray-700 text-center bg-gray-400 px-4 py-2 m-2">
    Item that can grow or shrink if needed
  </div>
</div>

Responsive

To control how a flex item both grows and shrinks at a specific breakpoint, add a {screen}: prefix to any existing utility class. For example, use md:flex-1 to apply the flex-1 utility at only medium screen sizes and above.

Customizing

Flex Values

By default Tailwind provides four flex utilities. You change, add, or remove these by editing the theme.flex section of your Tailwind config.

// tailwind.config.js
module.exports = {
theme: {
flex: {
      '1': '1 1 0%',
      auto: '1 1 auto',
-     initial: '0 1 auto',
+     inherit: 'inherit',
      none: 'none',
+     '2': '2 2 0%',
}
}
}

Responsive and State Variants

By default, only responsive variants are generated for flex utilities.

You can control which variants are generated for the flex utilities by modifying the flex property in the variants section of your tailwind.config.js file.

For example, this config will also generate hover and focus variants:

// tailwind.config.js
module.exports = {
variants: {
    // ...
-   flex: ['responsive'],
+   flex: ['responsive', 'hover', 'focus'],
}
}

Disabling

If you don't plan to use the flex utilities in your project, you can disable them entirely by setting the flex property to false in the corePlugins section of your config file:

// tailwind.config.js
module.exports = {
corePlugins: {
    // ...
+   flex: false,
}
}
