Question

我正在尝试将一组与左侧对齐的Bootstrap卡居中。

我需要将容器div中心置于主网格中，然后将牌向左对齐。

我尝试在主行中使用“ justify-content-center”，但是它不起作用。

<div class="container-fluid" style="  background-color: #999;" >
  <div class="row">
      <div class=col-1></div>
      <div class=col-10>

            <div class="container-fluid mt-4" style="  background-color: #ff0;" >
                <div class="row justify-content-left">
                    <div class="col-auto mb-3">
                        <div class="card" style="width: 18rem;">
                            <div class="card-body">
                                <h5 class="card-title">Card title</h5>
                                <h6 class="card-subtitle mb-2 text-muted">Card subtitle</h6>
                                <p class="card-text">Some quick example text to build on the card title and make up the bulk of the card's content.</p>
                                <a href="#" class="card-link">Card link</a>
                                <a href="#" class="card-link">Another link</a>

Answer 2

根据我的理解，您想要的是网格居中并且左侧的卡片在列中对齐。

因此只需将以下 CSS 添加到行：

.col-centered {
  float: none;
  margin: 0 auto !important;
  width: 80%;
  background: lightblue;
}

并替换您的 HTML 行：

<div class="row justify-content-left">

与此一起：

<div class="row col-centered">

然后向左对齐卡添加 CSS ：

.card {
    float: left;
 }
