BASE - Document Base url

Syntax

<BASE>

Attribute Specifications

HREF=url (base url reference)
TARGET=FrameTarget (frame to render links in)

Contained in

Description

The BASE element defines the document's base url for resolving relative urls contained within the document. A document cannot contain more than one BASE element. When present, the BASE element must appear in the HEAD, prior to any elements that include a partial url.

HREF

BASE's HREF attribute, required in HTML 4.0 Strict, specifies the absolute url used to resolve relative urls. See Using Relative URLs for more details on using and resolving relative urls.

Most Web pages do not require an explicit base url since the document's url is a suitable base. An explicit base url is only required when the same document may be accessed at different urls or when the document has no url (e.g., sending an HTML document by e-mail).

TARGET

The TARGET attribute is used with frames to specify in which frame all links in document should be rendered by default. The target frame specified by BASE can be overridden by a given link using the link's TARGET attribute.

If no frame with the specified target name exists, the links are rendered in a new window unless overridden by the user. Special frame names begin with an underscore:

_blank renders the links in a new, unnamed window
_self renders the links in the current frame
_parent renders the links in the immediate FRAMESET parent
_top renders the links in the full, unframed window
