I have tested many solutions found through google, none suffice.
I built this template originally in straight html using a table and am trying to translate it into a wordpress theme.
The two sidebars do not stretch to the height of the containing element: wrapper, as one would expect with height: 100%. I have noted through research the height percent property relates to height of viewport (screen height), but ....
Per w3schools the height percent property "Defines the height in percent of the containing block".
Per HTML DOM: "The height property has effect only on block-level elements or on elements with absolute or fixed position. "
This theme requires width of content area to stretch to fill screen width. So I can't see how to meet the HTML DOM.
Faux columns is not a solution, as I need to maintain the bottom border effect on all three columns and the right column contains only a rotating background image.
This issue seems to be pretty prevalent. Who of you out there has an answer for me?
