Refining Markup Details
In this lesson, we will refine some markup details and learn to work with URLs in HTML.
In the chapters you have already gone through, you have seen a number of HTML elements, and you have utilized them in exercises and samples. Most exercises had a “How It Works” section that explained important details, however, there were important subtleties not treated there.
In this section you will learn the most important nitty-gritty markup details that are crucial to know before diving into deeper subjects.
