Editing Hyperlink (section)

===HTML===
{{Main article|HTML element#Anchor}}
[[Tim Berners-Lee]] saw the possibility of using hyperlinks to link any information to any other information over the [[Internet]]. Hyperlinks were therefore integral to the creation of the [[World Wide Web]]. Web pages are written in the hypertext mark-up language [[HTML]].

This is what a hyperlink to the home page of the [[W3C organization]] could look like in HTML code:

<syntaxhighlight lang="html">
<a href="https://www.w3.org/">W3C organization website</a>
</syntaxhighlight>

This HTML code consists of several [[HTML element|tags]]:
* The hyperlink starts with an anchor opening tag '''<nowiki><a</nowiki>''', and includes a hyperlink reference '''<nowiki>href="https://www.w3.org/</nowiki>"''' to the '''[[URL]]''' for the page. (The URL is enclosed in quotes.)
* The [[URL]] is followed by '''>''', marking the end of the anchor opening tag.
* The words that follow identify what is being linked; this is the only part of the code that is ordinarily visible on the screen when the page is rendered, but when the cursor hovers over the link, many browsers display the target URL somewhere on the screen, such as in the lower left-hand corner.
* Typically these words are underlined and colored (for example, blue for a link that has not yet been visited and purple for a link already visited).
* The anchor closing tag ('''<nowiki></a></nowiki>''') terminates the hyperlink code.
* The '''<nowiki><a></nowiki>''' tag can also consist of various [[HTML attribute|attributes]] such as the "rel" attribute which specifies the relationship between the current document and linked document.

[[Webgraph]] is a [[Graph (discrete mathematics)|graph]], formed from [[web page]]s as vertices and hyperlinks, as directed edges.
