The chief power of HTML comes from its ability to link text and/or an image to another document or section of a document. A browser highlights the identified text or image with color and/or underlines to indicate that it is a hypertext link (often shortened to hyperlink or just link).

HTML's single hypertext-related tag is <A>, which stands for anchor. To include an anchor in your document:

1. start the anchor with <A (include a space after the A)
2. specify the document you're linking to by entering the parameter HREF="filename" followed by a closing right angle bracket (>)
3. enter the text that will serve as the hypertext link in the current document
4. enter the ending anchor tag: </A> (no space is needed before the end anchor tag)

Here is a sample hypertext reference to a file called headings.html:

    <A HREF="headings.html">Headings</A>

This entry makes the word Headings the hyperlink to the document headings.html, which is in the same directory as the first document.
