## What it is
layerJS is a JavaScript UI/UX library for composing mobile app-like interfaces in pure HTML using a Stage-Frame concept. Frames are content containers exchanged within stage viewports via animated transitions like swipes and fades, triggered by plain HTML links or touch gestures.

## Use cases
- build mobile app-like navigation in a web app
- create animated sliders and carousels with plain HTML
- implement swipeable sub-pages with touch gestures
- add pull-down menus and lightboxes declaratively
- create parallax backgrounds and floating menu layers
- compose multi-screen single-page app layouts

## When to choose
- you want app-style animated UI transitions without a heavy framework
- you prefer declaring UI structure with HTML attributes over JavaScript code
- you need touch gesture-driven navigation like swipes and pull-down menus

## When to avoid
- you need a full component-based frontend framework with state management
- your project uses React, Vue, or Angular and needs deep framework integration
- you need actively maintained software with recent releases

## Facets
