/*
Apply these class names to form elements:
* required (not blank)
* validate-number (a valid number)
* validate-digits (digits only, spaces allowed.)
* validate-alpha (letters only)
* validate-alphanum (only letters and numbers)
* validate-date (a valid date value)
* validate-email (a valid email address)
* validate-url (a valid URL)
* validate-date-au (a date formatted as; dd/mm/yyyy)
* validate-currency-dollar (a valid dollar value)
* validate-one-required (At least one checkbox/radio element must be selected in a group)
* validate-not-first (Selects only, must choose an option other than the first)
* validate-not-empty (Selects only, must choose an option with a value that is not empty)
Also, you can specify this attribute for text, passwird and textarea elements:
* minlength="x" (where x is the minimum number of characters)
