Examples

Basic example

Use flex-<number> utilities like flex-1 to allow a flex item to grow and shrink as needed, ignoring its initial size:

<!-- [!code word:flex-1] -->
<div class="flex">
  <div class="w-14 flex-none ...">01</div>
  <div class="w-64 flex-1 ...">02</div>
  <div class="w-32 flex-1 ...">03</div>
</div>

Initial

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

<!-- [!code word:flex-initial] -->
<div class="flex">
  <div class="w-14 flex-none ...">01</div>
  <div class="w-64 flex-initial ...">02</div>
  <div class="w-32 flex-initial ...">03</div>
</div>

Auto

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

<!-- [!code word:flex-auto] -->
<div class="flex ...">
  <div class="w-14 flex-none ...">01</div>
  <div class="w-64 flex-auto ...">02</div>
  <div class="w-32 flex-auto ...">03</div>
</div>

None

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

<!-- [!code word:flex-none] -->
<div class="flex ...">
  <div class="w-14 flex-none ...">01</div>
  <div class="w-32 flex-none ...">02</div>
  <div class="flex-1 ...">03</div>
</div>

Using a custom value

Use the flex-[<value>] syntax to set the flex based on a completely custom value:

<div class="flex-[3_1_auto] ...">Lorem ipsum dolor sit amet...</div>

For CSS variables, you can also use the flex-(<custom-property>) syntax:

<div class="flex-(--my-flex) ...">Lorem ipsum dolor sit amet...</div>

This is just a shorthand for flex-[var(<custom-property>)] that adds the var() function for you automatically.

Responsive design

Prefix a flex utility with a breakpoint variant like md: to only apply the utility at medium screen sizes and above:

<div class="flex-none md:flex-1 ...">Lorem ipsum dolor sit amet...</div>
