How to align content of a div to the bottom

Answer 1

Seems to be working:

#content {
    /* or just insert a number with "px" if you're fighting CSS without lesscss.org :) */
    vertical-align: -@header_height + @content_height;

    /* only need it if your content is 
,
     * if it is inline (e.g., ) will work without it */
    display: inline-block;
}

Using less makes solving CSS puzzles much more like coding than like... I just love CSS. It's a real pleasure when you can change the whole layout (without breaking it :) just by changing one parameter.
