HTML Links are the basical entity of hypertextual navigation.
There are several kinds of links. Standard links are used to send the visitor to another page that can be located under the same domain or in another domain. These links can be relative or absolute: relative links are specified starting from the actual page location on the server and absolute links include the full URL of the linked page.

This is an example of a relative link to another page of this site, in the same folder as this page:This link is relative as well but points to a page contained in another folder; the ../ specifies that the path of the document starts from the superior directory:This link is absolute, you just have to specify the full URL of the page you are linking to: You'll have noticed that there's a target attribute, it's used to specify where the destination page will be displayed:You can use links also to send the visitors to specific section of your page: say you have a really long page and want to split it in several directly reachable sections without creating separate pages, well you can add anchors where you want to create break points:and then you can link to the specific section specifying it into the linked URL, in this way the linked page will scroll until the destination section is displayed:Another genre of link is the email link, with this kind of link when a visitor clicks it will result in his mail client to open a new email message with a precomipled recipient (or more than one), subject and body. If you don't specify these fields they will be empty.If you want to send the email to multiple addresses just put a comma between them.
