Basic usage

Initial

Use flex-initial to allow a flex item to shrink but not grow, taking into account its initial size:

<div class="flex">
  <div class="flex-none w-14 h-14">
    01
  </div>
  <div class="flex-initial w-64 ...">
    02
  </div>
  <div class="flex-initial w-32 ...">
    03
  </div>
</div>

Flex 1

Use flex-1 to allow a flex item to grow and shrink as needed, ignoring its initial size:

<div class="flex">
  <div class="flex-none ...">
    01
  </div>
  <div class="flex-1 w-64 ...">
    02
  </div>
  <div class="flex-1 w-32 ...">
    03
  </div>
</div>

Auto

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

<div class="flex ...">
  <div class="flex-none ...">
    01
  </div>
  <div class="flex-auto w-64 ...">
    02
  </div>
  <div class="flex-auto w-32 ...">
    03
  </div>
</div>

None

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

<div class="flex ...">
  <div class="flex-none w-14 h-14 ...">
    01
  </div>
  <div class="flex-none ...">
    02
  </div>
  <div class="flex-1 ...">
    03
  </div>
</div>

Applying conditionally

Hover, focus, and other states

Tailwind lets you conditionally apply utility classes in different states using variant modifiers. For example, use hover:flex-1 to only apply the flex-1 utility on hover.

<div class="flex-none hover:flex-1">
  <!-- ... -->
</div>

For a complete list of all available state modifiers, check out the Hover, Focus, & Other States documentation.

Breakpoints and media queries

You can also use variant modifiers to target media queries like responsive breakpoints, dark mode, prefers-reduced-motion, and more. For example, use md:flex-1 to apply the flex-1 utility at only medium screen sizes and above.

<div class="flex-none md:flex-1">
  <!-- ... -->
</div>

To learn more, check out the documentation on Responsive Design, Dark Mode and other media query modifiers.

Using custom values

Customizing your theme

By default, Tailwind provides four flex utilities. You can customize these values by editing theme.flex or theme.extend.flex in your tailwind.config.js file.

tailwind.config.js

module.exports = {
  theme: {
    extend: {
      flex: {
        '2': '2 2 0%'
      }
    }
  }
}

Learn more about customizing the default theme in the theme customization documentation.

Arbitrary values

If you need to use a one-off flex value that doesn’t make sense to include in your theme, use square brackets to generate a property on the fly using any arbitrary value.

<div class="flex-[2_2_0%]">
  <!-- ... -->
</div>
