How do I change column width and background

[NJC]

I was finally able to change my layout from 2-column to 3-column. But now the column widths are all up in the air and the background is out of sync.How do I correct this?My blog is at: Not Just CricketThe CSS code is: As follows in the CodeBoxI would like to have the left and right sidebar widths at around 170.The left column's left edge without any margin.The right column's right edge without any margin.The space between the (right edge of the left sidebar) and the (left edge of the central content column) to be around 16.The space between the (left edge of the right sidebar) and the (right edge of the central content column) to be around 16.If it might make things easier, I dont mind (for now) if the background color is a single flat color- white. Once the columns and backgrounds are set, I will try and do the color change.Any help will be very much appreciated.
