html - 用图像填充整个 Bootstrap 4 模态主体

Question

我有一个包含旋转木马的 Bootstrap 4 模态框，我想用大小为 700px x 450px 的图像填充模态框的整个主体，图像的左/上/右周围没有边框/边距/填充.我希望页脚可见，这样我就可以放置一些文本和一个关闭按钮

这是 Codepen

这是我试图通过图像外观实现的类似示例，请忽略与图像无关的任何内容。

<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 而不是 .modal-body 中。并从 .modal-body 中删除 padding。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。
