Polyfill
When I started to compose web pages it was always a battle to get compatabilty between browsers
Basically a "kluge".
Something that should not work, but does.
A device assembled from components intended for disparate purposes.

What it says on the Wikipedia page:
"
In web development, a polyfill is code that implements a feature on web browsers that do not support the feature.
Most often, it refers to a JavaScript library that implements an HTML5 or CSS web standard, either an established
standard (supported by some browsers) on older browsers, or a proposed standard (not supported by any browsers)
on existing browsers.
Formally, "a polyfill is a shim for a browser API".
Polyfills allow web developers to use an API regardless of whether or not it is supported by a browser, and usually
with minimal overhead. Typically they first check if a browser supports an API, and use it if available, otherwise
using their own implementation.[1][2] Polyfills themselves use other, more supported features, and thus different
polyfills may be needed for different browsers.
The term is also used as a verb: polyfilling is providing a polyfill for a feature.
