It works by extracting text content and wrapping individual units (letters, words, or lines) in styled spans, then applying CSS animations with calculated delays to create fluid, sequential effects.
Features:
- HTML Attribute Control: Configure animations entirely through data attributes without writing JavaScript code.
- Multiple Animation Types: Support for letter-by-letter, word-by-word, and line-by-line animation modes.
- Sequential Logic: Built-in timing system for proper animation sequencing and completion.
- Animation Order Options: Sequential, randomized, and reverse animation patterns for varied visual effects.
- Custom Delay Control: Precise timing control with single or multiple delay values for complex animation rhythms.
- Duration Override: Base duration settings that override CSS animation durations when needed.
- Dynamic Content Support: Re-initialization capability for content loaded after initial page render.

How to use it:
1. Install AnimText and import it into your main JavaScript file.
npm i animtext npm i @hellouxpavel/cssanimation
import animtext from "animtext"; import "@hellouxpavel/cssanimation";
2. For direct use in an HTML file, add the {css}animation library to your <head> and the AnimTex.js before your closing </body> tag.
<link rel="stylesheet" href="/path/to/cssanimation.min.css" /> <script src="/path/to/animtext.min.js"></script>
3. To animate an element, you need two things: the cssanimation class and a data-at-* attribute.
class="cssanimation": This class is required. It’s the hook that AnimText uses to find elements to process.data-at-sequence="ca__fx-fadeIn": This attribute tells AnimText to animate the element’s text letter-by-letter (sequence) using theca__fx-fadeInanimation from the {css}animation library.
<h1 class="cssanimation" data-at-sequence="ca__fx-fadeIn">CSSScript</h1>
4. AnimText supports multiple animation patterns through specific data attributes:
data-at-sequence: Animates letters from first to last in orderdata-at-random: Randomizes letter animation sequencedata-at-reverse: Animates letters from last to firstdata-at-word: Animates complete words sequentiallydata-at-line: Animates text lines based on line breaks or custom separators
5. The data-at-delay attribute accepts single or multiple delay values in milliseconds:
<p class="cssanimation" data-at-sequence="ca__fx-fadeIn" data-at-delay="50 100 200"> Varied timing rhythm </p>
6. Set consistent animation duration across all units:
<h3 class="cssanimation" data-at-word="ca__fx-slideInUp" data-at-base-duration="800"> All words animate for 800ms </h3>
7. Control how lines are split using the separator attribute:
<p class="cssanimation" data-at-line="ca__fx-fadeIn" data-at-separator="dot"> First sentence. Second sentence. Third sentence. </p>
8. Assign different animations to each unit by space-separating class names:
<h2 class="cssanimation" data-at-word="ca__fx-fadeIn ca__fx-moveFromTop ca__fx-bounceInLeft"> Each word gets different animation </h2>
9. For content loaded after initial page render, manually trigger re-initialization:
animtext.init();
This scans the DOM for new elements with the cssanimation class and applies appropriate animations.
FAQs
Q: Why are my animations not working?
A: The most common reason is forgetting to include the cssanimation library’s stylesheet. AnimText only creates the <span> structure and applies timing; it relies on an external library like cssanimation for the actual keyframe definitions. Also, confirm the target element has the cssanimation class.
Q: Can I use my own CSS animation classes instead of the ones from cssanimation?
A: Yes. AnimText is class-agnostic. You can pass any CSS class name to the data-at-* attributes as long as that class and its @keyframes are defined in your project’s CSS.
Q: Can I mix data-at-word and data-at-line on the same element?
A: No. Only one data-at-* type is processed per element. Chain them on different elements if needed.
