Bookmarks allow us to link directly to a specific section of a page. Say for instance, I have a page broken into four sections, numbered 1-4. If I wanted to put a link at the top of the page that linked to each of the sections, I'd use the name attribute of the anchor tag - the same tag later used to create the actual link. To name a section the HTML code is <a name = "bookmark"></a>. Then, to call the link, all I have to do is reference the name of the page, followed by the number sign (#) and the bookmark name <a href="#bookmark">Goto Bookmark</a>.
The result would be:
