The i element marks text that stands apart from surrounding prose because it has a different role, such as alternative text. Browsers typically render the marked text in italics. section 12.2.6 section 12.6
Mark up a title
Use the i element when a title or other alternative text needs to look different from the surrounding sentence: <p> Let's visit the land of Narnia, first introduced to us by C.S. Lewis in <i>The Lion, the Witch, and the Wardrobe</i> (1950). </p> The browser displays the title in italic type. section 12.2.6
Choose the element according to the text's role: use strong for important text, b for keywords, em for emphasis, and i for alternative text. Mark the exact words manually when precise control matters. section 12.2.6 section 12.6
