在 Bootstrap 4 行中对齐 SVG 元素

Posted 2023-03-06

【中文标题】在 Bootstrap 4 行中对齐 SVG 元素

【英文标题】：Align SVG element in Bootstrap 4 row

【发布时间】：2018-05-22 12:30:42

【问题描述】：

我想将图标 (<svg>) 和文本都对齐到容器的中心。我想要图标和文本之间的小间距：

|      ICON TEXT      |

https://jsbin.com/tatomas/edit?html,css,output

我有可用的 Bootstrap 4 (Flexbox)。但我不知道该怎么做。尤其是 <svg> 很难对齐 - 我无法将它移动到任何地方。我尝试将它们放在 .row 中，每个 .col 中，但 SVG 保持在颜色的中心...

我怎样才能做到这一点（有或没有 BS 网格）？？

【参考方案1】：

使用现有的标记，需要做两件主要的事情：

col 有预定义的填充，需要重新设置

例如使用 text-align: right 将 SVG 向右对齐

此外，没有设置宽度的 SVG 元素可能会在某些浏览器上造成问题，所以我在这里提供了一个（在其标记中添加了 width="80"）

有了这个，您现在可以为col 元素添加您选择的边距或填充（在下面的替代方案中，添加到section-* 元素），在这些示例中我使用了边距。

作为替代方案，您可以删除 col 元素并将内置类 justify-content-center 添加到 row 元素 (<div class="row justify-content-center">)

除了它们的标记之外，两者之间的主要区别在于图标/标题之间的小间隙/边距位于其父中心的第一个样本中，或者它不是，图标/标题中心作为一个群体。
