@zirkeldesign/tailwindcss-stuck-variant v0.2.1

Tailwind CSS stuck variant

Adds a stuck: and group-stuck: variant to Tailwind CSS to style elements and child nodes which use the .sticky utility. Unfortunately since there is currently no CSS selector for :stuck Elements, this variant relies on a JavaScript helper, which uses the IntersectionObserver on those elements.

Installation

# Using npm
npm install @zirkeldesign/tailwindcss-stuck-variant

# Using yarn
yarn add @zirkeldesign/tailwindcss-stuck-variant

// tailwind.config.js
module.exports = {
  variants: {
    height: ["responsive", "stuck"],
    // or with extending the default variants
    // @see https://tailwindcss.com/docs/configuring-variants#extending-default-variants
    backgroundColor: ({ after }) => after(["stuck", "group-stuck"]),
    // or in Tailwind CSS >= v2.0
    extend: {
      backgroundColor: ["stuck", "group-stuck"],
    },
  },
  plugins: [
    // Other plugins...
    require("@zirkeldesign/tailwindcss-stuck-variant"),
  ],
};

// app.js
require("@zirkeldesign/tailwindcss-stuck-variant/src/observer")();
