<div id="intro"><h2>Introduction</h2></div> <div class="standout"><h3>Classes and IDs in CSS</h3> <p>Classes and IDs are super easy in CSS. You're using them right now!</p></div> <h3>Regular HTML Selectors</h3> <p>If you don't bother with a class or ID, an HTML element just gets the regular CSS styling for that element—or the default styling if you don't specify any particular styling on the stylesheet. </p>
