Hey thanks for the link it was a great description only one thing i have a question you said an id can only be used once. Does this mean that as with a class you could do this

<h1 class="bar">Hello, World</h1>
<h1 class="bar">Hello, World</h1>
<h1 class="bar">Hello, World</h1>

but you could not do that with the ID more than once within the document

You're welcome. Yes, you shouldn't have more than one element with the same id. However, you can have as many elements as you want with the same class.

That's right. ID "identifies" a single element. CLASS defines any number of elements having the same characteristics (of the class).
