tw-animate-css

A collection of Tailwind CSS v4.0 utilities for creating beautiful animations. Includes ready-to-use animations accordion-down, accordion-up and caret-blink, as well as a set of utilities for creating your own animations.

---

This package is a replacement for tailwindcss-animate. It embraces the new CSS-first architecture, providing a pure CSS solution for adding animation capabilities to your Tailwind CSS project without relying on the legacy JavaScript plugin system or having to define all keywords from scratch.

Getting Started

NPM

1. Install the package with npm:

   npm install -D tw-animate-css

2. Add the following line to your app.css or globals.css file:

   @import "tw-animate-css";

3. Start using the animations!

   <!-- Add an animated fade and zoom entrance -->
   <div class="animate-in fade-in zoom-in">...</div>
   
   <!-- Add an animated slide to top-left exit -->
   <div class="animate-out slide-out-to-top slide-out-to-left">...</div>
   
   <!-- Control animation duration -->
   <div class="... duration-300">...</div>
   
   <!-- Control animation delay -->
   <div class="... delay-150">...</div>
   
   <!-- And so much more! -->

ℹ️ NOTE
The above guide works for esbuild, Vite and probably other bundlers too. If you are using a different bundler, the syntax may differ. Let me know how it works and I'll update the documentation.

Manual Download

1. Download the tw-animate.css file from GitHub and place it next to your app.css or globals.css file.

2. Add the following line to your app.css or globals.css file:

   @import "./tw-animate.css";

3. Start using the animations!

   <!-- Add an animated fade and zoom entrance -->
   <div class="animate-in fade-in zoom-in">...</div>
   
   <!-- Add an animated slide to top-left exit -->
   <div class="animate-out slide-out-to-top slide-out-to-left">...</div>
   
   <!-- Control animation duration -->
   <div class="... duration-300">...</div>
   
   <!-- Control animation delay -->
   <div class="... delay-150">...</div>
   
   <!-- And so much more! -->

Usage

Enter/Exit Animations

To keep the README concise, I'll define a few variables:

• <io>: Specify the type of animation. This can be in for enter or out for exit animations.
• <dir>: Specify the direction of the slide. This can be in-from-top, in-from-bottom, in-from-left, in-from-right, out-to-top, out-to-bottom, out-to-left or out-to-right.
• *: Specify a value to apply. See list of possible values.

  data-state="show"
>
  <p>

Notes on Compatibility

ℹ️ NOTE
I use only a small portion of the original plugin, so it might not be a 100% compatible drop-in replacement. If you notice any inconsistencies, feel free to contribute to this repository by opening a pull-request.
