我想根据宽度的百分比值设置时钟的高度和宽度以填充以下html td（因为时钟需要具有相同的宽度和高度才能成为圆形）。此外，当我尝试使用中心标签时，时钟没有居中。谁能推荐另一种方法来根据 td 调整时钟尺寸并使时钟居中。

提前谢谢您，如果我太含糊，请告诉我是否需要解释！

HTML

<td colspan="1" style="width: 26%; height: 250px;";>
  <center>
  <div id="clock" style="position: relative; height:250px;"> 
<div style="position: absolute; left: 0px; top: 0px;" id='seconds'></div>
<div style="position: absolute; left: 0px; top: 0px;" id='hours'></div>
    <div style="position: absolute; left: 0px; top: 0px;" id='minutes'></div>
  </div>
  </center>
</td>

该<center>标签基本上被忽略了，因为#clock div 将占据 td 的整个宽度。

尝试...删除<center>和</center>放...

text-align:center;

...进入#clock div的样式。

我不能说这会起作用，因为我无法使用页面上的 jqxGauge 访问它。

更新：

jqxGauge 有宽度和高度的选项...

$('#gauge').jqxGauge({ width: '20%', height: '30%', radius: '50%' });
