html代碼: <ul?class="countdown"> ????<li>?<span?class="days"?id="my_day">00</span> ????????<p?class="days_ref">天</p> ????</li> ????<li?class="seperator">.</li> ????<li>?<span?class="hours"?id="my_hour">00</span> ????????<p?class="hours_ref">時</p> ????</li> ????<li?class="seperator">:</li> ????<li>?<span?class="minutes"?id="my_minite">00</span> ????????<p?class="minutes_ref">分</p> ????</li> ????<li?class="seperator">:</li> ????<li>?<span?class="seconds"?id="my_second">00</span> ????????<p?class="seconds_ref">秒</p> ????</li> </ul>
