Examples

Basic example

Use max-w-<number> utilities like max-w-24 and max-w-64 to set an element to a fixed maximum width based on the spacing scale:

max-w-96

max-w-80

max-w-64

max-w-48

max-w-40

max-w-32

max-w-24

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

Using a percentage

Use max-w-full or max-w-<fraction> utilities like max-w-1/2 and max-w-3/4 to give an element a percentage-based maximum width:

max-w-9/10

max-w-3/4

max-w-1/2

max-w-1/3

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

Using the container scale

Use utilities like max-w-sm and max-w-xl to set an element to a fixed maximum width based on the container scale:

<div class="max-w-md ...">
  <!-- content -->
</div>

Using breakpoints container

Use the container utility to set a responsive fixed maximum width that changes based on the current breakpoint:

<div class="container">
  <!-- content -->
</div>

You can also center the container and add horizontal padding:

<div class="container mx-auto px-4">
  <!-- content -->
</div>

Matching the viewport

Use the max-w-screen utility to make an element span at most the entire width of the viewport:

<div class="max-w-screen">
  <!-- ... -->
</div>

Alternatively, you can match the width of the large, small or dynamic viewports using the max-w-lvw, max-w-svw, and max-w-dvw utilities.

Removing the maximum width

Use the max-w-none utility to remove an element's assigned maximum width under a specific condition, like at a particular breakpoint:

<div class="max-w-md md:max-w-none">
  <!-- ... -->
</div>

Using a custom value

Use the max-w-[<value>] syntax to set the maximum width based on a completely custom value:

<div class="max-w-[220px] ...">
  <!-- ... -->
</div>

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

<div class="max-w-(--my-max-width) ...">
  <!-- ... -->
</div>

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

Responsive design

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

<div class="max-w-sm md:max-w-lg ...">
  <!-- ... -->
</div>

Learn more about using variants in the variants documentation.

Customizing your theme

The max-w-<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.
