我正在建立一个记分卡，其中将显示一些有关您健康状况的不同参数。这是我的下面的代码

这是浏览器中的外观

如您所见，有不同的健康参数，例如Sugar level，Hemoglobin level等。但是，如果仔细观察，分数并不是位于其各自参数的中心，尤其是对于{{1} }和Water。现在，我不确定如何相对于分数上方的参数居中。

我了解了诸如Security和relative之类的CSS位置，但是我不确定如何针对其他元素使用它。我还尝试了absolute到display: flex; align-items: center;的div，但无济于事。

如何相对于参数定位数字？

您在对主h1进行样式化时实际上找到了解决方案。它只需要多一点方法。 content-justify：center。

方法1

  

我正在编写此方法，因为，您正在将bootstrap 3与flex一起使用。   您可以切换到4。no-floating-promises 

.sub-score {
  color: #00FF00;
}

.category {
  color: DodgerBlue;
}

.center {
  display: flex!important;
  align-items: center!important;
  justify-content: center!important;
}

.column {
  flex-direction: column!important;
}

将以下代码复制到空白html文件中，然后在浏览器中将其打开。您将获得所需的输出。

您可以在text-align: center;和<h2>上使用<h3>来使文本居中。

您可以使用text-center引导程序类在中心对齐元素

示例jsfiddle

答案 4 :(得分：0)

HTML表非常适合此目的：

<table>

  <tr>
    <th><h3 class="category">Sugar Level</h3></th>
    <th><h3 class="category">Hemoglobin Level</h3></th>
    <th><h3 class="category">Water</h3></th>
    <th><h3 class="category">Blood Pressure</h3></th>
    <th><h3 class="category">Security</h3></th>
  </tr>

  <tr>
    <td><h2 class="sub-score">46</h2></td>
    <td><h2 class="sub-score">82</h2></td>
    <td><h2 class="sub-score">46</h2></td>
    <td><h2 class="sub-score">54</h2></td>
    <td><h2 class="sub-score">46</h2></td>
  </tr>

</table>

然后，您可以使用CSS来设置表格的填充样式，并以自己喜欢的方式设置边距。这将与所有单元格保持一致。

请注意，以这种方式使用H2和H3并非“ SEO友好”，您可能希望将该文本放在跨度之内。但是如果您只是进行测试就可以。
