Dom Collection: Exploring the Dom Collection's API

In this example, the use of several key Dom Collection methods is explored. Given the markup in the source section, you can invoke any of the methods by clicking on them; the Source is updated, as is its in-browser appearance (Render). In the Outupt section, you can review the elements that are selected or affected (or, in a few cases, the JavaScript return value) of the function you invoked.
