Tag Definition and Usage
The <base> tag specifies the default URL and default target for all relative links on a page.
Only one <base> element can be used in a document. The <base> tag must be inside the <head> element.
Tips and Notes
Tip: Place the <base> tag as the first element in the <head> section so that other elements in the head section can use the information from the <base> element.
Note: If the <base> tag is used, it must have either the href attribute, the target attribute, or both.

None.
