Before We Make The Sidebar Page, Let's
Learn What A "target" Is And What It Does
For A Link. Also Why We "name" A "frame".

A "name" Is Given To Each Of The Two
"frames" In Our Frames Page. The Sidebar
Page Sits In One "frame" And The Main Page
Sits In Another "frame". We Will "name" each
Of These "frames" When We Build Our Frames Page.
A "target" Specifies Which "frame" To
Direct The Link To.
