/**************** ESSENTIAL STYLES ***************/
/* This first group of styles are most important for the function of Superfish.
 * The more cosmetic styling rules are grouped together below under the heading
 * ORIGINAL SKIN.
 *
 * Note that this CSS file will create the kind of menu demonstrated on the main
 * page of the Superfish documentation, ie. top tier of nav is horizontal, with
 * subsequent tiers vertical.

This is because the JS needs to be able to control hide and reveal delays and animations without the pure CSS rule intruding. Note the tag selector ul.nav instead of just .nav - this gives it the most specificity of all and makes it trump all other positioning rules, including the .superfish overrides below */
