## What it is
Featherlight is an ultra-slim (~4kB) jQuery lightbox plugin supporting images, ajax content, iframes, and custom DOM content. It uses minimal namespaced CSS, is fully customizable via config objects or data attributes, and includes a gallery extension.

## Use cases
- open images in a lightbox on click
- display ajax-loaded html in a modal dialog
- show iframe content in a popup overlay
- build an image gallery with lightbox navigation
- add a lightweight modal to a jQuery site
- open a hidden div as a lightbox

## When to choose
- your site already uses jQuery and you need a tiny lightbox
- you want minimal, easily overridable CSS with no inline styles
- you need image, ajax, and iframe lightbox support out of the box

## When to avoid
- starting a new project without jQuery dependency
- you need a modern framework-native modal component
- you need heavy features like zoom, touch gestures, or video players

- function: ui-components, animation
