Installation

With npm

npm install tailwind-gradient-mask-image

With yarn

yarn add tailwind-gradient-mask-image

Configuration

Add the plugin to your tailwind.config.js

{
    plugins: [require("tailwind-gradient-mask-image")]
}

Usage

<div class="gradient-mask-t-0">
    ...
</div>

The plugin creates classes with prefix gradient-mask-. After the prefix follows a direction shorthand and the gradient start percentage.

The class above matches the css

.class {
    mask-image: linear-gradient(to top, rgba(0, 0, 0, 1.0) 0%, transparent 100%);
}

Using gradient-mask-none will set the CSS property to mask-image: none. This can be used in combination of breakpoints for device-specific behaviors

Variations

Direction shorthands

{
  t: "to top",
  tr: "to top right",
  r: "to right",
  br: "to bottom right",
  b: "to bottom",
  bl: "to bottom left",
  l: "to left",
  tl: "to top left",
} 

The gradient start percentages go from 0% to 100% with 10% gaps.

Arbitrary values

You can use arbitrary values to specify unique steps towards a specific direction

<div class="gradient-mask-t-[transparent,rgba(0,0,0,1.0)_30px,rgba(0,0,0,0.5)_40%]">
    ...
</div>

The class above matches the following css

.class {
    mask-image: linear-gradient(to top, transparent, rgba(0,0,0,1.0) 30px, rgba(0,0,0,0.5) 40%, transparent 100%)
}

A transparent at 100% will always be set to keep a specific direction

You can always add transparent_80% at the end of your abitrary value to have the last 20% fully masked
