What is the default behavior of the target attribute in the <base> element?

The default behavior of the target attribute in the <base> element is to show the result in the current browsing context.

By default, the target attribute is set to _self, which means that the linked document will open in the same frame as it was clicked. This is the standard behavior unless another target is specified. Other possible values include _blank for opening in a new window or tab, _parent for opening in the parent frame, and _top for opening in the full body of the window.
