flex-basis

Examples

Using the spacing scale

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

<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:

<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:

<div class="flex flex-row">  <div class="basis-1/3">01</div>  <div class="basis-2/3">02</div></div>

Referencing a variable

Use the basis-(<custom-property>) syntax to set the basis based on a custom property:

<div class="basis-(--my-basis) ...">  <!-- ... --></div>

Using a custom value

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

<div class="basis-[30vw] ...">  <!-- ... --></div>

Responsive design

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

<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>

Learn more about using variants in the variants documentation.

Customizing your theme

Use the --container-* theme variables to customize the fixed-width basis utilities in your project:

@theme {  --container-4xs: 14rem; }

Now the basis-4xs utility can be used in your markup:

<div class="basis-4xs">  <!-- ... --></div>

Additionally, customizing your spacing scale will also update the basis-<number> scale:

@theme {  --spacing: 1px; }
