@tailwindcss/line-clamp

A plugin that provides utilities for visually truncating text after a fixed number of lines.

Installation

Install the plugin from npm:

npm install -D @tailwindcss/line-clamp

Then add the plugin to your tailwind.config.js file:

// tailwind.config.js
module.exports = {
  theme: {
    // ...
  },
  plugins: [
    require('@tailwindcss/line-clamp'),
    // ...
  ],
}

Usage

Use the line-clamp-{n} utilities to specify how many lines of text should be visible before truncating:

<p class="line-clamp-3">
  Et molestiae hic earum repellat aliquid est doloribus delectus. Enim illum odio porro ut omnis dolor debitis natus. Voluptas possimus deserunt sit delectus est saepe nihil. Qui voluptate possimus et quia. Eligendi voluptas voluptas dolor cum. Rerum est quos quos id ut molestiae fugit.
</p>

To remove any line-clamping, use line-clamp-none:

<p class="line-clamp-3 md:line-clamp-none">
  Et molestiae hic earum repellat aliquid est doloribus delectus. Enim illum odio porro ut omnis dolor debitis natus. Voluptas possimus deserunt sit delectus est saepe nihil. Qui voluptate possimus et quia. Eligendi voluptas voluptas dolor cum. Rerum est quos quos id ut molestiae fugit.
</p>

Note that the line-clamp-{n} set other properties like display and overflow in addition to -webkit-line-clamp which are not unset by line-clamp-none, so depending on what you are trying to achieve you may need to explicitly override those properties with utilities like flex or overflow-visible as well.

Utilities are for clamping text up to 6 lines are generated by default:

Class	CSS
`line-clamp-1`	`overflow: hidden;` `display: -webkit-box;` `-webkit-box-orient: vertical;` `-webkit-line-clamp: 1;`
`line-clamp-2`	`overflow: hidden;` `display: -webkit-box;` `-webkit-box-orient: vertical;` `-webkit-line-clamp: 2;`
`line-clamp-3`	`overflow: hidden;` `display: -webkit-box;` `-webkit-box-orient: vertical;` `-webkit-line-clamp: 3;`
`line-clamp-4`	`overflow: hidden;` `display: -webkit-box;` `-webkit-box-orient: vertical;` `-webkit-line-clamp: 4;`
`line-clamp-5`	`overflow: hidden;` `display: -webkit-box;` `-webkit-box-orient: vertical;` `-webkit-line-clamp: 5;`
`line-clamp-6`	`overflow: hidden;` `display: -webkit-box;` `-webkit-box-orient: vertical;` `-webkit-line-clamp: 6;`
`line-clamp-none`	`-webkit-line-clamp: unset;`
