ステッパー

<%# Markup for the stepper (steps / wizard) demo.
    The steps (ol + button) and the prev/next buttons are grouped under one controller
    element. The library manages the current step number, sets data-state (complete /
    current / upcoming) on each li, sets aria-current="step" on the current step's button,
    enforces out-of-range / linear constraints, and fires the change event. The circle /
    line / number look is in demo.css. %>
