## What it is
Webshims Lib is a modular, capability-based polyfill-loading library that extends jQuery with HTML5 features in legacy browsers. It conditionally loads polyfills for canvas, forms, media, and other HTML5 APIs only when the browser lacks native support.

## Use cases
- polyfill HTML5 form validation and date inputs in old browsers
- add canvas and picture/srcset support to legacy browsers
- load polyfills conditionally based on feature detection
- support HTML5 audio/video in older browsers with jQuery
- backfill geolocation and getUserMedia in legacy browsers

## When to choose
- maintaining a legacy jQuery-based site that must support old browsers like IE
- you need capability-based conditional polyfill loading for HTML5 features

## When to avoid
- starting a new modern project - the library is deprecated and incompatible with jQuery 3.x
- you only need ES6+ polyfills rather than HTML5 DOM/form features
- your target browsers already support the HTML5 features natively

## Facets
- artifact type: library
- maturity: abandoned
- function: ui-components, form-handling, image-processing, audio-processing, video-processing
- domain: web-development, frontend, browser-extensions
- platform: browser
- tags: polyfill, html5, jquery, capability-detection, deprecated, legacy-browsers, javascript
