## What it is
PIE (Progressive Internet Explorer) is an IE attached behavior (PIE.htc) that lets Internet Explorer 6-8 recognize and render CSS3 box decoration properties like border-radius, box-shadow, border-image, multiple backgrounds, and linear gradients. It is applied via a single CSS behavior rule on elements needing CSS3 decoration support in legacy IE.

## Use cases
- render rounded corners in IE6-8
- support box-shadow in old Internet Explorer
- display CSS3 linear gradients in legacy IE
- make border-image work in IE
- avoid sprite image hacks for rounded corners in IE
- support multiple background images in IE

## When to choose
- you must support Internet Explorer 6-8 with CSS3 decorations
- maintaining a legacy site that still targets old IE browsers

## When to avoid
- building any modern website (all current browsers support CSS3 natively)
- you only need to support IE9 or later
- starting a new project

## Facets
- artifact type: library

- domain: web-development, frontend, web-design
- platform: windows, browser
