May not be what you're looking for. but if you use the web developer tools for firefox, you can select Information -> Display id and class details. This will display the ID and class information of every element on the page. Also using CSS -> View Style Information will allow you to hover over elements and have their class and id hierarchy displayed individually when you hover over them. I only offer this solution because I assume you don't want the functionality available to the user, but rather as a tool to debug the website.
