}</div><p style="margin-top: 15px;">在表格单元格中添加 <code>class="blink-text"</code> 即可实现此效果。</p></div><footer><p>HTML表格红色粗体闪烁文字示例</p></footer></div>
</body>
</html>

2. 最少代码

/* 闪烁动画 */
@keyframes blink {0% { opacity: 1; }50% { opacity: 0.3; }100% { opacity: 1; }
}
.blink-text {animation: blink 1.2s infinite;color: #ff0000;font-weight: bold;
}
<td class="status-cell blink-text">高风险</td>
