This part modified by Chris Smith to set minimum height for a <div> from class name
for valeswood.com

Set CSS class of div to 'minheight***' for a minimum height of ***px. 

This is useful where the div has a visible border and contains text and a floated image, 
to prevent the image from extending beyond the border if the user viewing the page changes 
the font size.
