Examples#

Basic example#

Use utilities like shadow-sm and shadow-lg to apply different sized outer box shadows to an element:

{

shadow-md

shadow-lg

shadow-xl

}

<!-- [!code classes:shadow-md,shadow-lg,shadow-xl] -->
<div class="shadow-md ..."></div>
<div class="shadow-lg ..."></div>
<div class="shadow-xl ..."></div>

Changing the opacity#

Use the opacity modifier to adjust the opacity of the box shadow:

{

shadow-xl

shadow-xl/20

shadow-xl/30

}

<!-- [!code classes:shadow-xl,shadow-xl/20,shadow-xl/30] -->
<div class="shadow-xl ..."></div>
<div class="shadow-xl/20 ..."></div>
<div class="shadow-xl/30 ..."></div>

The default box shadow opacities are quite low (25% or less), so increasing the opacity (to like 50%) will make the box shadows more pronounced.

Setting the shadow color#

Use utilities like shadow-indigo-500 and shadow-cyan-500/50 to change the color of a box shadow:

{

shadow-cyan-500/50

shadow-blue-500/50

shadow-indigo-500/50

}

<!-- [!code classes:shadow-cyan-500/50,shadow-blue-500/50,shadow-indigo-500/50] -->
<button class="bg-cyan-500 shadow-lg shadow-cyan-500/50 ...">Subscribe</button>
<button class="bg-blue-500 shadow-lg shadow-blue-500/50 ...">Subscribe</button>
<button class="bg-indigo-500 shadow-lg shadow-indigo-500/50 ...">Subscribe</button>

By default colored shadows have an opacity of 100% but you can adjust this using the opacity modifier.

Adding an inset shadow#

Use utilities like inset-shadow-xs and inset-shadow-sm to apply an inset box shadow to an element:

{

inset-shadow-2xs

inset-shadow-xs

inset-shadow-sm

}

<!-- [!code classes:inset-shadow-2xs,inset-shadow-xs,inset-shadow-sm] -->
<div class="inset-shadow-2xs ..."></div>
<div class="inset-shadow-xs ..."></div>
<div class="inset-shadow-sm ..."></div>

You can adjust the opacity of an inset shadow using the opacity modifier, like inset-shadow-sm/50. The default inset shadow opacities are quite low (5%), so increasing the opacity (to like 50%) will make the inset shadows more pronounced.

Setting the inset shadow color#

Use utilities like inset-shadow-indigo-500 and inset-shadow-cyan-500/50 to change the color of an inset box shadow:

{

inset-shadow-indigo-500

inset-shadow-indigo-500/50

}

<!-- [!code classes:inset-shadow-indigo-500,inset-shadow-indigo-500/75] -->
<div class="inset-shadow-sm inset-shadow-indigo-500 ..."></div>
<div class="inset-shadow-sm inset-shadow-indigo-500/50 ..."></div>

By default colored shadows have an opacity of 100% but you can adjust this using the opacity modifier.

Adding a ring#

Use ring or ring-<number> utilities like ring-2 and ring-4 to apply a solid box-shadow to an element:

{

ring

ring-2

ring-4

}

<!-- [!code classes:ring,ring-2,ring-4] -->
<button class="ring ...">Subscribe</button>
<button class="ring-2 ...">Subscribe</button>
<button class="ring-4 ...">Subscribe</button>

By default rings match the currentColor of the element they are applied to.

Setting the ring color#

Use utilities like ring-indigo-500 and ring-cyan-500/50 to change the color of a ring:

{

ring-blue-500

ring-blue-500/50

}

<!-- [!code classes:ring-blue-500,ring-blue-500/50] -->
<button class="ring-2 ring-blue-500 ...">Subscribe</button>
<button class="ring-2 ring-blue-500/50 ...">Subscribe</button>

By default rings have an opacity of 100% but you can adjust this using the opacity modifier.

Adding an inset ring#

Use inset-ring or inset-ring-<number> utilities like inset-ring-2 and inset-ring-4 to apply a solid inset box-shadow to an element:

{

inset-ring

inset-ring-2

inset-ring-4

}

<!-- [!code classes:inset-ring,inset-ring-2,inset-ring-4] -->
<button class="inset-ring ...">Subscribe</button>
<button class="inset-ring-2 ...">Subscribe</button>
<button class="inset-ring-4 ...">Subscribe</button>

By default inset rings match the currentColor of the element they are applied to.

Setting the inset ring color#

Use utilities like inset-ring-indigo-500 and inset-ring-cyan-500/50 to change the color of an inset ring:

{

inset-ring-blue-500

inset-ring-blue-500/50

}

<!-- [!code classes:inset-ring-blue-500,inset-ring-blue-500/50] -->
<button class="inset-ring-2 inset-ring-blue-500 ...">Subscribe</button>
<button class="inset-ring-2 inset-ring-blue-500/50 ...">Subscribe</button>

By default inset rings have an opacity of 100% but you can adjust this using the opacity modifier.

Removing a box shadow#

Use the shadow-none, inset-shadow-none,ring-0, and inset-ring-0 utilities to remove an existing box shadow from an element:

{

shadow-none

}

<!-- [!code classes:shadow-none] -->
<div class="shadow-none ..."></div>
