To explore the various ways in which we can let a plugin's user customize its behavior, we need an example that has several settings that can be tweaked and modified. As our example, we'll replicate a feature of CSS by using a more brute-force JavaScript approach--an approach that is more suitable for demonstration than for production code. Our plugin will simulate a shadow on an element by creating a number of copies that are partially transparent overlaid in different positions on the page:

(function($) {
