base Element

 

Module

The base element is declared by the XHTML 1.1 Base Module

This is the only element in this Module.

Description

The base element is used (within the document head) to specify an absolute base URI against which all relative URIs in the document should be resolved. The #REQUIRED href attribute is used for this purpose. No document may contain more than one base element.

If a base element is not present within a document, the base URI is taken to be URI of the document itself.

Note that, for an object element, the base URI may be changed using the codebase attribute.

#REQUIRED Attributes

The href attribute is #REQUIRED on the base element.
