如何在容器内居中对齐并获得统一的宽度

Question

我需要水平居中对齐下图中显示的所有内容。

我还需要使所有 table 单元格的宽度相同，因为它们似乎是根据超棒的字体图标大小自动调整的。

我该怎么做？

我的HTML

<section id="Four" class="wrapper style3">

Answer 1

你应该使用 margin: auto;为您的内部或容器 class

.inner {
     ...
     margin: auto;
     ....

}

Answer 2

您可以将 flexbox 与 flex-grow 和 flex-basis 结合使用，使列的宽度相等并填充行。

.row {
  display: flex;
}
.row .columns {
  flex-grow: 1;
  flex-basis: 0;
  margin: 0 1em;
  background: #eee;
}

          <p class="text-box">25 YEARS OF SERVICE</p>
        </div>
</section>
</div>
</div>

或者您可以为列指定特定的宽度，然后使用 justify-content 将它们居中

.row {
  display: flex;
  justify-content: center;
}
.row .columns {
  width: 150px;
  margin: 0 1em;
  background: #eee;
}

Answer 3

我还建议使用 display:flex;。

这里有一个例子https://jsfiddle.net/znggcgaq/

.row{
  display: flex;
  flex-wrap: wrap;
}

.row .columns {
  margin: 5px;
  flex-grow: 1;
}

这是一个很好的指南，它是如何工作的：https://css-tricks.com/snippets/css/a-guide-to-flexbox/

在我的示例中，我允许项目包装在容器内 div。

Answer 4

根据我在此处提出的另一个问题，我找到了问题最后步骤的解决方案：

我已经使用了上面发布的提示：

#statistics .row {
            display: flex;
            justify-content: center;
    }

    #statistics .row .columns {
            width: 150px;
            margin: 0 1em;
            background: #fff;
    }

但在此之后，一切在 Dreamweaver 上看起来都不错，但在浏览器中就不行了。问题是 CSS 指令顺序，因为它们不是 "grid" CSS 部分中的最后一个。我把它们放在 CSS 部分的最后一个，并且它最终居中，正如我想要的那样
