Creating a link to an email address is almost identical to creating a link to a web page. But instead of the URL designate mailto: email address.
If you want create a link to a document that opens a new browser window, set parameter target="_blank" of the a tag.
Large documents are easier to read if they have a table of contents with links to relevant sections.
In addition to hypertext, you can use images as links. The image in this case must be place between the tags <a href=...> and </a>.
You can not remove the underline from hyperlinks with HTML tags. For this purpose, cascading style sheets are used (CSS).
By default, if you click on a link a document opens in the current window or frame. If necessary, this can be changed by setting parameter target in the a tag.
