Every HTML attribute has an attribute node in the DOM tree. Two of the most popular HTML attributes to work with are the id and class attributes. Using the id attribute, you can uniquely identify and access an individual HTML element. There should only be one element with a certain id value on a single HTML page. With the class attribute, you can identify and access a group of HTML elements. Multiple elements can share the same class value. Here is an example:

<h1 id="article_title">Example Page</h1>
<p class="article_body">Paragraph 1</p>
<p class="article_body">Paragraph 2</p>
