我试图用Bootstrap 4在页面中间居中我的容器。到目前为止我还没有成功。任何帮助都将不胜感激。

我在Codepen建立了它。io，所以你们可以玩它，让我知道什么工作，因为我的想法……

使用这个引导4个类:

Method1:

父:d表和子:d-table-cell & align-middle & text-center

eg:

<div class="tab-icon-holder d-table bg-light">
   <div class="d-table-cell align-middle text-center">
     <img src="assets/images/devices/Xl.png" height="30rem">
   </div>
</div>

如果你想让父母圆:

<div class="tab-icon-holder d-table bg-light rounded-circle">
   <div class="d-table-cell align-middle text-center">
     <img src="assets/images/devices/Xl.png" height="30rem">
   </div>
</div>

这两个自定义CSS类如下:

.tab-icon-holder {
  width: 3.5rem;
  height: 3.5rem;
 }
.rounded-circle {
  border-radius: 50% !important
}

最后的用法可以是这样的:

<div class="col-md-5 mx-auto text-center">
    <div class="d-flex justify-content-around">
     <div class="tab-icon-holder d-table bg-light rounded-circle">
       <div class="d-table-cell align-middle text-center">
         <img src="assets/images/devices/Xl.png" height="30rem">
       </div>
     </div>

     <div class="tab-icon-holder d-table bg-light rounded-circle">
       <div class="d-table-cell align-middle text-center">
         <img src="assets/images/devices/Lg.png" height="30rem">
       </div>
     </div>

     ...

    </div>
</div>

Method2: 你可以使用以下方法:

父项:h-100 d-table mx-auto 和 d-table-cell align-middle

Method3:

你可以使用以下方法:

父项:d-flex align-items-center

如果你想让内容水平居中:

父级:d-flex align-items-center justify-content-center

你可以通过使父容器伸缩并添加align-items来垂直对齐你的容器:

body {
  display:flex;
  align-items:center;
}

Bootstrap 5和blazor web组件:

<div class="d-flex align-items-center justify-content-center min" style="height: 50vh">
<button class="btn btn-outline-success mx-2">Register</button>
<button class="btn btn-outline-primary mx-2" style="width:123.44px">Login</button></div>
