React实现翻页时钟的代码示例

<div class="container">
    <ul class="flip">
        <li>
            <div class="up">
                <div class="content">0</div>
            </div>
            <div class="down">
                <div class="content">0</div>
            </div>
        </li>
        <li>
            <div class="up">
                <div class="content">1</div>
            </div>
            <div class="down">
                <div class="content">1</div>
            </div>
        </li>
    </ul>
</div>
