I have a blank div class that is called spacer ... it has a blue background and a width of 100% of the container (the body) ...
What I have found is that the spacer will not DISPLAY unless I toss some character in it. I can color the character blue so it is hidden, but that is so inelegant.
What is the CORRECT way to do this.

Just enter   ; inside your spacer div, but without the space before the semicolon. Alternatively, you could use break tags (<br>) to fill in the space, or a transparent spacer image set to the height you need.
Like :empty , :blank will select elements that contain nothing at all, or contain only an HTML comment. But, :blank will also select elements that include whitespace, which :empty will not. At the time of this writing, :blank is part of the CSS Selectors Level 4 draft, and is not supported by any browser.
A div (or any container element) is considered empty if it does not contain any other elements, text, or whitespace such as spaces or line breaks.
Give it a height.
Otherwise, with no content, it has zero height and is effectively invisible.
