The
<base>
element allows you to set a prefix that will automatically be attached to the URL indicated by any link on that page, allowing you to avoid repetitive code if all links on a page point to the same server.
Note
The <base>
element is an empty element(i.e it doesnt require an ending tag)
The <base>
element requires an href attribute set to the absolute URL of an internet directory. (e.g : href="http://www.domain.com/files/images/")
The element must be placed inside the <head>..</head>
element.
