如何使用 css 使一个文本相对于另一个文本居中？

Question

我正在构建一个记分卡，它将显示您的健康状况的一些不同参数。下面是我的代码

<!doctype html>
<html lang="en">

    <title>Scorecard</title>
    <style>
        .sub-score {
            margin-left: 20%;
            color: #00FF00;

        }

        .category {

            <div class="col-lg-2 col-sm-3">

            <div class="col-lg-2 col-sm-3">

                <h2 class="sub-score">46<h2>

这是它在浏览器中的样子

如您所见，有不同的健康参数，例如 Sugar level、Hemoglobin level 等。但如果您仔细观察，分数并不在各自参数的中心，尤其是 Water 和 Security。现在我不确定如何根据分数上方的参数将其居中。

我阅读了 css 中的位置，例如 relative 和 absolute，但我不确定如何将其用于另一个元素。我也试过 display: flex; align-items: center; 到 sub-score div 但没有用。

如何根据参数定位数字？

Answer 1

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

Answer 2

您可以使用 text-center bootstrap class 将您的元素居中对齐

样本jsfiddle

Answer 3

Html table非常适合这个目的：

<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 设置 table 的内边距和边距的样式。它对所有单元格都是一致的。

请注意，以这种方式使用 H2 和 H3 不是 'SEO-friendly'，您可能希望将该文本放在 span 等中。但如果你只是测试也没关系。

Answer 4

您在设计主 h1 样式时确实找到了解决方案。它只需要多一点方法。 content-justify : center.

方法一

I'm writing this method because, you are using flex with bootstrap 3. So you can switch to 4. See also.

.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，然后在浏览器中打开它。你会得到你想要的输出。
