A Shadowbox "adapter" is a small helper file that makes it easy to use Shadowbox with a given JavaScript framework. Since most JavaScript frameworks tend to contain a basic set of very similar functions (for retrieving style information on elements or handling events, for example) it is not necessary to tie Shadowbox to a particular framework. Instead, the adapter can use the underlying framework that is already loaded on the page to reuse some of the code. If you do not see an adapter for your favorite framework in this directory, feel free to create your own and implement the same interface as the others. It may then be used the same as you would use any other.
