## What it is
Flexie is a JavaScript polyfill that brings the legacy 2009 CSS3 Flexible Box Model to browsers lacking native support, such as IE 6-9 and Opera 10+. It uses Selectivizr's engine to parse stylesheets and emulate flexbox properties like box-orient, box-align, and box-pack.

## Use cases
- support flexbox layout in IE 6-9
- polyfill CSS3 box model in legacy browsers
- normalize flexbox inconsistencies across browsers
- use display: box in old Opera versions

## When to choose
- you must support legacy browsers like IE 6-9 with the old 2009 flexbox spec

## When to avoid
- you need the modern flexbox spec - no polyfill exists here for it
- starting a new project - all modern browsers support flexbox natively
- you need an actively maintained library - last release was 2016

## Facets
- artifact type: library
- maturity: abandoned
- function: ui-components, css-framework
- domain: frontend, web-development
- platform: browser
- tags: css3-flexbox, polyfill, legacy-browser-support, javascript
