title: Menu hover effect
body: <p>I would like to create a hover effect like the left category menu on this demo page <a href="http://themeforest.net/item/mazine-wordpress-theme-a-wp-ecommerce-theme/full_screen_preview/198602" rel="nofollow">http://themeforest.net/item/mazine-wordpress-theme-a-wp-ecommerce-theme/full_screen_preview/198602</a></p>
  
  <p>I tried to add padding-left:7px; in the css file, but this does not look the same.</p>
