/**
 * Hide elements from all users.
 *
 * Used for elements which should not be immediately displayed to any user. An
 * example would be collapsible details that will be expanded with a click
 * from a user. The effect of this class can be toggled with the jQuery show()
 * and hide() functions.

 * Hide elements visually, but keep them available for screen readers.
 *
 * Used for information required for screen reader users to understand and use
 * the site where visual display is undesirable. Information provided in this
 * manner should be kept concise, to avoid unnecessary burden on the user.
 * "!important" is used to prevent unintentional overrides.
