1,2,3,4 are the real killers 😕 because even if you tossed in #4 (even with an !important on the width value) to your CSS, the inlined #2 & hardcoded #3 would override it. #3 is setup as a "10% / 80% / 10%" layout (as hardcoded HTML, not CSS) for using both L and R side-columns, and a different percentage for just a single L or R side-column. This leaves the body_col getting a different percentage for each of the three variations.
