Utilities for setting the height of an element.

Examples

Basic example

Use h-<number> utilities like h-24 and h-64 to set an element to a fixed height based on the spacing scale:

h-96

h-80

h-64

h-48

h-40

h-32

h-24

<div class="h-96 ...">h-96</div><div class="h-80 ...">h-80</div><div class="h-64 ...">h-64</div><div class="h-48 ...">h-48</div><div class="h-40 ...">h-40</div><div class="h-32 ...">h-32</div><div class="h-24 ...">h-24</div>

Using a percentage

Use h-full or h-<fraction> utilities like h-1/2 and h-2/5 to give an element a percentage-based height:

h-full

h-9/10

h-3/4

h-1/2

h-1/3

<div class="h-full ...">h-full</div><div class="h-9/10 ...">h-9/10</div><div class="h-3/4 ...">h-3/4</div><div class="h-1/2 ...">h-1/2</div><div class="h-1/3 ...">h-1/3</div>

Matching viewport

Use the h-screen utility to make an element span the entire height of the viewport:

<div class="h-screen">  <!-- ... --></div>

Matching dynamic viewport

Use the h-dvh utility to make an element span the entire height of the viewport, which changes as the browser UI expands or contracts:

Scroll the viewport to see the viewport height change

<div class="h-dvh">  <!-- ... --></div>

Matching large viewport

Use the h-lvh utility to set an element's height to the largest possible height of the viewport:

Scroll the viewport to see the viewport height change

<div class="h-lvh">  <!-- ... --></div>

Matching small viewport

Use the h-svh utility to set an element's height to the smallest possible height of the viewport:

Scroll the viewport to see the viewport height change

<div class="h-svh">  <!-- ... --></div>

Setting both width and height

Use utilities like size-px, size-4, and size-full to set both the width and height of an element at the same time:

size-16

size-20

size-24

size-32

size-40

<div class="size-16 ...">size-16</div><div class="size-20 ...">size-20</div><div class="size-24 ...">size-24</div><div class="size-32 ...">size-32</div><div class="size-40 ...">size-40</div>

Using a custom value

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

<div class="h-[32rem] ...">  <!-- ... --></div>

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

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

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

Responsive design

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

<div class="h-1/2 md:h-full ...">  <!-- ... --></div>

Learn more about using variants in the variants documentation.

Customizing your theme

The h-<number> and size-<number> utilities are driven by the --spacing theme variable, which can be customized in your own theme:

@theme {  --spacing: 1px; }

Learn more about customizing the spacing scale in the theme variable documentation.
