I've been scouring both the CSS file and the home.php file, comparing them to other sites I've done with the Lifestyle template that all look fine, and I'm evidently not seeing something obvious...
(Here are some other sites using the Lifestye template I'm working on that don't have this 'broken home page' problem' :
