html - 如何在盒子/容器中水平和垂直居中对齐文本？

Question

我正在尝试创建一个如下所示的网页:

Download page

我使用 bootstrap 并创建行以将三个下载选项彼此对齐。然后，我在这些行中创建了容器(以复制框)并将文本和下载图标水平居中对齐。不幸的是，我不确定如何在容器中垂直居中对齐文本和图标。任何人都可以帮忙吗？我当前的设计如下所示:

我的代码如下:

.download {
  font: Verdana, Helvetica, Arial, sans-serif;
  color: RGB(112, 112, 112);
  font-size: 18px;
  text-align: center;
  padding: 5px;
}

.download:hover {
  color: rgb(227, 111, 30);
  cursor: pointer;
}

#download-icon {
  font-size: 80px;
  float: left;
}

.container-border {
  border-style: solid;
  border-color: rgb(0, 143, 197);
  padding: 5px;
  min-height: 120px;
}

<div class="container">
  <div class="row">
    <div class="col-xs-4">
      <div class="container-border">
        <i class="material-icons" style="color:rgb(0,143,197);" id="download-icon">file_download</i>
        <p class="download"> Download list of charities that have <b> not submitted </b> data yet </p>
      </div>
    </div>
  </div>
</div>

编辑:感谢大家的回答!我真的很感激他们。对我来说，它通过简单地调整我的内容边界类来工作:

.container-border {
border-style: solid;
border-color: rgb(0, 143, 197);
padding: 5px;
min-height: 120px;
display: flex;
align-items: center;
/* vertical center */
}

您不需要使用 FlexBox 使事情复杂化。请使用类似这样的表格布局或 line-height 和 vertical-align 组合:

.download {
  font: Verdana, Helvetica, Arial, sans-serif;
  color: RGB(112, 112, 112);
  font-size: 18px;
  text-align: center;
  padding: 5px;
}

.download:hover {
  color: rgb(227, 111, 30);
  cursor: pointer;
}

#download-icon {
  font-size: 80px;
  vertical-align: middle;
  line-height: 120px;
}

#download-icon + span {
  vertical-align: middle;
  line-height: 1;
}

.container-border {
  border-style: solid;
  border-color: rgb(0, 143, 197);
  padding: 5px;
  min-height: 120px;
}

<div class="container">
  <div class="row">
    <div class="col-xs-4">
      <div class="container-border">
        <i class="material-icons" style="color:rgb(0,143,197);" id="download-icon">file_download</i>
        <span class="download"> Download list of charities that have <b> not submitted </b> data yet </span>
      </div>
    </div>
  </div>
</div>
