Effects

mask-type

Utilities for controlling how an SVG mask is interpreted.

ClassStyles
mask-type-alpha
mask-type: alpha;
mask-type-luminance
mask-type: luminance;

Examples

Basic example

Use the mask-type-alpha and mask-type-luminance utilities to control the type of an SVG mask:

mask-type-alpha

mask-type-luminance

<svg>
<mask id="blob1" class="mask-type-alpha fill-gray-700/70">
<path d="..."></path>
</mask>
<image href="/img/mountains.jpg" height="100%" width="100%" mask="url(#blob1)" />
</svg>
<svg>
<mask id="blob2" class="mask-type-luminance fill-gray-700/70">
<path d="..."></path>
</mask>
<image href="/img/mountains.jpg" height="100%" width="100%" mask="url(#blob2)" />
</svg>

When using mask-type-luminance the luminance value of the SVG mask determines visibility, so sticking with grayscale colors will produce the most predictable results. With mask-alpha, the opacity of the SVG mask determines the visibility of the masked element.

Responsive design

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

<mask class="mask-type-alpha md:mask-type-luminance ...">
<!-- ... -->
</mask>
