用图像填充整个Bootstrap 4模态实体

Question

我有一个包含旋转木马的Bootstrap 4模态，我想用700px x 450px大小的图像填充模态的整个主体，在图像的左/上/右周围没有边框/边距/填充。我希望页脚可见，因此我可以放置一些文本和关闭按钮

这里是Codepen

这是我要通过图像外观实现的类似示例，请忽略所有非图像。

<div class="container">
  <h1 class="display-4 text-center mb-4">Sample Modal</h1>

  <div class="row mb-4">
    <div class="col text-center">
      <a href="#" class="btn btn-lg btn-primary" data-toggle="modal" data-target="#largeModal">Click to open Modal</a>
    </div>
  </div>

  <!-- modal -->
  <div class="modal fade" id="largeModal" tabindex="-1" role="dialog" aria-labelledby="basicModal" aria-hidden="true">
    <div class="modal-dialog modal-lg">
      <div class="modal-content">
        <div class="modal-body">
           <!-- carousel -->

Answer 1

您应该将width放在.modal-content中，而不是.modal-body。然后从padding中删除.modal-body。这是修改后的CSS：

.modal-content {
   width: 700px;
}
.modal-body {
   padding: 0;
}

希望它能解决您的问题。
