/* FORMS */

/* Simple form layouts.
 *
 * Use the "vertical" class to make the labels sit above the input fields:
 *
 *     Label
 *     [        ]
 *
 *     [x] Checkbox
 *
 *     [Submit]
 *
 *
 * Use the "horizontal" class if you want a more "horizontal" layout:
 *
 *     Label    [       ]
 *
 *     Another  [       ]
 *
 *              [x] Checkbox
 *
 *              [Submit]
 *
 * You need to explicitly add one of the layout classes to make it easier to use
 * forms as simple UI elements.
