Examples#

Using the spacing scale#

Use basis-<number> utilities like basis-64 and basis-128 to set the initial size of flex items based on the spacing scale:

{

01
02
03
}

<!-- [!code classes:basis-64,basis-128] -->
<div class="flex flex-row">
  <div class="basis-64">01</div>
  <div class="basis-64">02</div>
  <div class="basis-128">03</div>
</div>

Using the container scale#

Use utilities like basis-xs and basis-sm to set the initial size of flex items based on the container scale:

{

01
02
03
04
}

<!-- [!code classes:basis-3xs,basis-2xs,basis-xs,basis-sm] -->
<div class="flex flex-row">
  <div class="basis-3xs">01</div>
  <div class="basis-2xs">02</div>
  <div class="basis-xs">03</div>
  <div class="basis-sm">04</div>
</div>

Using percentages#

Use basis-<fraction> utilities like basis-1/2 and basis-2/3 to set the initial size of flex items:

{

01
02
}

<!-- [!code classes:basis-1/3,basis-2/3] -->
<div class="flex flex-row">
  <div class="basis-1/3">01</div>
  <div class="basis-2/3">02</div>
</div>

Using a custom value#

Responsive design#

<!-- [!code classes:md:basis-1/3] -->
<div class="flex flex-row">
  <div class="basis-1/4 md:basis-1/3">01</div>
  <div class="basis-1/4 md:basis-1/3">02</div>
  <div class="basis-1/2 md:basis-1/3">03</div>
</div>
