有几个地方有错误,看起来是拼写错误:
1. 第4行应该是 `var now_time = new Date();` 而不是 `var now_time =new Data()`
2. 第5行应该是 `var end_time = new Date('2023-05-16 12:00:00');` 而不是 `var end_time = new Date('2023-5-16 12:00:00')`
3. 第8行应该是 `var min =Math.floor((time-hour*3600)/60);` 而不是 `var min =Math.floor((time-hour*60)/60);`
4. 第9行应该是 `var sec =Math.floor(time-hour*3600-min*60);` 而不是 `var sec =Math.floor(time-hour*3600-min*60);`
5. 第11行应该是 `hour = hour < 10 ? '0'+hour : hour;` 而不是 `hour = hour < 12?'0'+hour:hour`
6. 第12行应该是 `min = min < 10 ? '0'+min : min;` 而不是 `min = min < 12?'0'+min:min`
7. 第13行应该是 `sec = sec < 10 ? '0'+sec : sec;` 而不是 `sec = sec < 12?'0'+sec:sec`
修改后的代码如下:
```
<head>

flex-direction: column;

align-items: center;
