Anchor

The anchor element is primarily used for hyper-links, usually referred to as links, to other HTML documents. There are different types of document hyper-links.

Attribute	Description
	A link within or between documents
href	The value of the href attribute can be the URL of another page within the site, or a remote site. Or it can be the id of an element within the current page.
target	The value of "_blank" opens the linked to page in a new window.
title	The browser may show this as a tooltip when the user hovers over the link.

External Pages (Absolute URL): The URL assigned to the href attribute is an absolute URL, or the entire path to the remote resource. These are used to navigate to an external site.

Set the attribute target="_blank" to have the target web page launch in a new browser tab instead of replacing the contents of the current tab.

<a href="http://www.google.com" target="_blank">Google</a>

Internal Site Pages (Relative URL): The URL assigned to the href attribute is a relative URL, meaning that is is a path relative to the current web page that contains the hyper-link. It is used to link to another page within your site.

<!-- .. indicates one level up -->
<a href="../page1.html">Page 1</a>

<!-- same folder -->
<a href="page2.html">Page 2</a>

<!-- down into subDir folder -->
<a href="subDir/page3.html">Page 3</a>

Internal Page Reference (within the same page): The anchor element can specify a special href syntax to indicate that the hyper-link is to a different location in the current document. The target location must be an element with an attribute named id that uniquely identifies the element. The anchor's href attribute value must be of the form "#[id-of-target-element]".

<a href="#section1">Section 1</a>

<!-- Lots of other stuff here -->
<section id="section1">
    <p>This is section 1</p>
