The DOM Explained

The Document Object Model is a concept that can be confusing and difficult to communicate – which is why I really like this article from Chris Coyier of CSS Tricks. He  describes the most common ways the DOM is misunderstood and sets it straight. While not a thorough technical treatise on the subject, it’s high level overview can be a great place to start to figure out this important idea.
