In #key# HTML: Hypertext Markup Language #key#, the **`<base>` tag** is used to enumerate the *base URL* to use for all relative URLs in an HTML document. There can only be a single `<base>` tag per document, and it should be between `<head>` tags.

#      
## Attributes
The `base` element supports [global attributes](https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes) in Hypertext markup language but does not support any event attributes. The `base` tag should possess at least one of the following attributes: `href` or `target`.
