Examples

Using an image mask

Use the mask-[<value>] syntax to set the mask image of an element:

<div class="mask-[url(/img/scribble.png)] bg-[url(/img/mountains.jpg)] ...">
  <!-- ... -->
</div>

Masking edges

Use utilities like mask-b-from-<value> and mask-t-to-<value> to add a linear gradient mask to a single side of an element:

mask-t-from-50%

mask-r-from-30%

mask-l-from-50% mask-l-to-90%

mask-b-from-20% mask-b-to-80%

<div class="mask-t-from-50% bg-[url(/img/mountains.jpg)] ..."></div>
<div class="mask-r-from-30% bg-[url(/img/mountains.jpg)] ..."></div>
<div class="mask-l-from-50% mask-l-to-90% bg-[url(/img/mountains.jpg)] ..."></div>
<div class="mask-b-from-20% mask-b-to-80% bg-[url(/img/mountains.jpg)] ..."></div>

Additionally, use utilities like mask-x-from-70% and mask-y-to-90% to apply a mask to two sides of an element at the same time:

mask-x-from-70% mask-x-to-90%

mask-y-from-70% mask-y-to-90%

<div class="mask-x-from-70% mask-x-to-90% bg-[url(/img/mountains.jpg)] ..."></div>
<div class="mask-y-from-70% mask-y-to-90% bg-[url(/img/mountains.jpg)] ..."></div>

By default, linear gradient masks transition from black to transparent, but you can customize the gradient colors using the mask-<side>-from-<color> and mask-<side>-to-<color> utilities.

Adding an angled linear mask

Use utilities like mask-linear-<angle>, mask-linear-from-20, and mask-linear-to-40 to add a custom linear gradient mask to an element:

mask-linear-50

-mask-linear-50

<div class="mask-linear-50 mask-linear-from-60% mask-linear-to-80% bg-[url(/img/mountains.jpg)] ..."></div>
<div class="-mask-linear-50 mask-linear-from-60% mask-linear-to-80% bg-[url(/img/mountains.jpg)] ..."></div>

Adding a radial mask

Use the mask-radial-from-<value> and mask-radial-to-<value> utilities to add a radial gradient mask to an element:

<div class="flex items-center gap-4">
  <img class="mask-radial-[100%_100%] mask-radial-from-75% mask-radial-at-left ..." src="/img/keyboard.png" />
  <div class="font-medium">
    <p class="font-mono text-xs text-blue-500 uppercase dark:text-blue-400">Speed</p>
    <p class="mt-2 text-base text-gray-700 dark:text-gray-300">Built for power users</p>
    <p class="mt-1 text-sm leading-relaxed text-balance text-gray-500">
      Work faster than ever with customizable keyboard shortcuts
    </p>
  </div>
</div>

By default, radial gradient masks transition from black to transparent, but you can customize the gradient colors using the mask-radial-from-<color> and mask-radial-to-<color> utilities.

Setting the radial position

Use utilities like mask-radial-at-bottom-left and mask-radial-at-[35%_35%] to set the position of the center of the radial gradient mask:

mask-radial-at-top-left

mask-radial-at-top

mask-radial-at-top-right

mask-radial-at-left

mask-radial-at-center

mask-radial-at-right

mask-radial-at-bottom-left

mask-radial-at-bottom

mask-radial-at-bottom-right

<div class="mask-radial-at-top-left mask-radial-from-100% bg-[url(/img/mountains.jpg)] ..."></div>
<div class="mask-radial-at-top mask-radial-from-100% bg-[url(/img/mountains.jpg)] ..."></div>
<div class="mask-radial-at-top-right mask-radial-from-100% bg-[url(/img/mountains.jpg)] ..."></div>
<div class="mask-radial-at-left mask-radial-from-100% bg-[url(/img/mountains.jpg)] ..."></div>
<div class="mask-radial-at-center mask-radial-from-100% bg-[url(/img/mountains.jpg)] ..."></div>
<div class="mask-radial-at-right mask-radial-from-100% bg-[url(/img/mountains.jpg)] ..."></div>
<div class="mask-radial-at-bottom-left mask-radial-from-100% bg-[url(/img/mountains.jpg)] ..."></div>
<div class="mask-radial-at-bottom mask-radial-from-100% bg-[url(/img/mountains.jpg)] ..."></div>
<div class="mask-radial-at-bottom-right mask-radial-from-100% bg-[url(/img/mountains.jpg)] ..."></div>

This is different from mask-position which sets the position of the mask image itself, not the radial gradient.

Setting the radial size

Use utilities like mask-radial-closest-corner and mask-radial-farthest-side to set the size of the radial gradient mask:

mask-radial-closest-side

mask-radial-closest-corner

mask-radial-farthest-side

mask-radial-farthest-corner

<div class="mask-radial-closest-side mask-radial-from-100% mask-radial-at-[30%_30%] bg-[url(/img/mountains.jpg)] ..."></div>
<div class="mask-radial-closest-corner mask-radial-from-100% mask-radial-at-[30%_30%] bg-[url(/img/mountains.jpg)] ..."></div>
<div class="mask-radial-farthest-side mask-radial-from-100% mask-radial-at-[30%_30%] bg-[url(/img/mountains.jpg)] ..."></div>
<div class="mask-radial-farthest-corner mask-radial-from-100% mask-radial-at-[30%_30%] bg-[url(/img/mountains.jpg)] ..."></div>

When setting a custom radial gradient size, the units you can use depend on the <ending-shape> of the gradient which is set to ellipse by default.

With mask-circle, you can only use a single fixed length, like mask-radial-[5rem]. Whereas with mask-ellipse, you can specify each axis as a fixed length or percentage, like mask-radial-[40%_80%].

Adding a conic mask

Use the mask-conic-from-<value>, mask-conic-to-<value> and mask-conic-<angle> utilities to add a conic gradient mask to an element:

Storage used: 75%

0.48 GB out of 2 GB remaining

<div class="flex items-center gap-5 rounded-xl bg-white p-4 shadow-lg ring-1 ring-black/5 dark:bg-gray-800">
  <div class="grid grid-cols-1 grid-rows-1">
    <div class="border-4 border-gray-100 dark:border-gray-700 ..."></div>
    <div class="border-4 border-amber-500 mask-conic-from-75% mask-conic-to-75% dark:border-amber-400 ..."></div>
  </div>
  <div class="w-0 flex-1 text-sm text-gray-950 dark:text-white">
    <p class="font-medium">Storage used: 75%</p>
    <p class="mt-1 text-gray-500 dark:text-gray-400"><span class="font-medium">0.48 GB</span> out of 2 GB remaining</p>
  </div>
</div>

By default, conic gradient masks transition from black to transparent, but you can customize the gradient colors using the mask-conic-from-<color> and mask-conic-to-<color> utilities.

Combining masks

Gradient mask utilities, like mask-radial-from-<value>, mask-conic-to-<value>, and mask-l-from-<value> can be combined to create more complex gradient masks:

<div class="mask-b-from-50% mask-radial-[50%_90%] mask-radial-from-80% bg-[url(/img/mountains.jpg)] ..."></div>
<div class="mask-r-from-80% mask-b-from-80% mask-radial-from-70% mask-radial-to-85% bg-[url(/img/mountains.jpg)] ..."></div>

This behavior relies on the fact that Tailwind sets the mask-composite property to intersect by default. Changing this property will affect how the gradient masks are combined.

Removing mask images

Use the mask-none utility to remove an existing mask image from an element:

<div class="mask-none">
  <!-- ... -->
</div>

Using a custom value

Use utilities like mask-linear-[<value>] and mask-radial-[<value>] to set the mask image based on a completely custom value:

<div class="mask-linear-[70deg,transparent_10%,black,transparent_80%] ...">
  <!-- ... -->
</div>

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

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

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

Responsive design

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

<div class="mask-radial-from-70% md:mask-radial-from-50% ...">
  <!-- ... -->
</div>

Learn more about using variants in the variants documentation.

Customizing your theme

Use the --color-* theme variables to customize the color utilities in your project:

@theme {
  --color-regal-blue: #243c5a; 
}

Now utilities like mask-radial-from-regal-blue,mask-conic-to-regal-blue, and mask-b-from-regal-blue can be used in your markup:

<div class="mask-radial-from-regal-blue">
  <!-- ... -->
</div>

Learn more about customizing your theme in the theme documentation.
