Question:

An _______adds to the basic functionality of a HTML tab.

Answer:

Adding Tab Space in HTML

Unlike with HTML space, there is no particular HTML tab character you could use. You could technically use the 	 entity as the tab is character 9 in the ASCII. Unfortunately, HTML parsers will simply collapse it into a single space due to the whitespace collapse principle.
