## What it is
Sequence.js is a responsive CSS animation framework for building step-based applications such as sliders, presentations, and banners. It handles the JavaScript logic for stepping between slides while letting developers style transitions with CSS classes like .seq-in and .seq-out.

## Use cases
- create an animated responsive image slider
- build a step-based presentation in the browser
- make an animated banner with CSS transitions
- add touch and keyboard navigation to a slideshow
- build a step-by-step product walkthrough
- create a custom carousel without heavy UI libraries

## When to choose
- you want full control over slide animations using plain CSS
- you need responsive, touch-enabled sliders or presentations
- you prefer styling transitions yourself rather than using preset animations

## When to avoid
- you need a maintained library with frequent updates and active support
- you want a batteries-included slider with prebuilt themes and no custom CSS
- your project uses modern frameworks where a React/Vue slider component fits better
