Flexbox & Grid
Utilities for controlling how flex items both grow and shrink.
| Class | Styles | 
|---|---|
| flex-<number> | flex: <number>; | 
| flex-<fraction> | flex: calc(<fraction> * 100%); | 
| flex-auto | flex: auto; | 
| flex-initial | flex: 0 auto; | 
| flex-none | flex: none; | 
| flex-(<custom-property>) | flex: var(<custom-property>); | 
| flex-[<value>] | flex: <value>; | 
Use flex-<number> utilities like flex-1 to allow a flex item to grow and shrink as needed, ignoring its initial size:
<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>Use flex-initial to allow a flex item to shrink but not grow, taking into account its initial size:
<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>Use flex-auto to allow a flex item to grow and shrink, taking into account its initial size:
<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>Use flex-none to prevent a flex item from growing or shrinking:
<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>Use the flex-[<value>] syntax to set the flex shorthand property based on a completely custom value:
<div class="flex-[3_1_auto] ...">  <!-- ... --></div>For CSS variables, you can also use the flex-(<custom-property>) syntax:
<div class="flex-(--my-flex) ...">  <!-- ... --></div>This is just a shorthand for flex-[var(<custom-property>)] that adds the var() function for you automatically.
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 ...">  <!-- ... --></div>Learn more about using variants in the variants documentation.
