how to size a div's height to its container height, using CSS?

Answer 1

I did something similar to KyokoHunter:

$('div.row').each(function(){
     var rowHeight = $(this).innerHeight();
     $(this).children('div.column').css('height',rowHeight);
});

This goes through every row in a div "table" and makes the heights all match, as long as the divs are classed accordingly.
