In this lesson you will learn how to make anchors.
Anchors are basically links to other areas of the same page.
You have most likely seen them somewhere. If you click on it, it does take you back to the top of the page. Other examples are when you are at a large page with a lot of different content, and at the top of the page there is often links to the different parts of the page. Suppose I put all the lessons of this tutorial on one HUGE page. Since people don't want to search for a certain lesson, I would put anchors to all the different lessons at the top for easy access.
