图片库缩略图大小 Bootstrap 4

Question

我有一个非常简单的响应式图片库，只有 6 个缩略图。在大中型设备中它显示完美。但是，在移动视图中，缩略图变得太小了。如果我添加填充，边距 "break" 并且它们不再对齐。没有 "breaking" 边距，有没有办法让它们变大一点？我贴了图片，这样更容易理解。

在下图中，您可以看到边距对齐，但缩略图太小了。

在下方您可以看到添加填充时发生的情况。缩略图变大了，但边距不再对齐。

.container {
  max-width: 98%;
  margin: 0 auto;
}

.image-container {
  background-color: #ffffff;
  padding: 10px;
}

.main-image-container img {
  max-width: 100%;
  height: auto;
}

.thumbnail-image-container img {
  max-width: 100%;
  height: auto;
}

    <div class="col-lg-7 image-container">

Answer 1

一种解决方案是向所有 col-* 类添加相同的填充。 Bootstrap 有名为 p-* 的填充类。下一个示例将 p-1 类添加到 main-image-container 和 thumbnail-image-container 元素。

.container {
  max-width: 98%;
  margin: 0 auto;
}

.image-container {
  background-color: #ffffff;
  padding: 10px;
}

.main-image-container img {
  max-width: 100%;
  height: auto;
}

.thumbnail-image-container img {
  max-width: 100%;
  height: auto;
}

<div class="container mt-4">
  <div class="row">

    <div class="col-lg-7 image-container">

      <div class="row">
        <div class="col-12 p-1 main-image-container img-fluid">
          <img src="https://placeholdit.co//i/1280x720?&text=Test">
        </div>
      </div>

      <div class="row pt-2">
        <div class="col-2 p-1 thumbnail-image-container img-fluid">
          <img src="https://placeholdit.co//i/1280x720?&text=Test">
        </div>
        <div class="col-2 p-1 thumbnail-image-container img-fluid">
          <img src="https://placeholdit.co//i/1280x720?&text=Test">
        </div>
        <div class="col-2 p-1 thumbnail-image-container img-fluid">
          <img src="https://placeholdit.co//i/1280x720?&text=Test">
        </div>
        <div class="col-2 p-1 thumbnail-image-container img-fluid">
          <img src="https://placeholdit.co//i/1280x720?&text=Test">
        </div>
        <div class="col-2 p-1 thumbnail-image-container img-fluid">
          <img src="https://placeholdit.co//i/1280x720?&text=Test">
        </div>
        <div class="col-2 p-1 thumbnail-image-container img-fluid">
          <img src="https://placeholdit.co//i/1280x720?&text=Test">
        </div>
      </div>

    </div>

  </div>
</div>

第二种解决方案是使用右 col-* 类将缩略图分成两行。就像下一个例子：

.container {
  max-width: 98%;
  margin: 0 auto;
}

.image-container {
  background-color: #ffffff;
  padding: 10px;
}

.main-image-container img {
  max-width: 100%;
  height: auto;
}

.thumbnail-image-container img {
  max-width: 100%;
  height: auto;
}

<div class="container mt-4">
  <div class="row">

    <div class="col-lg-7 image-container">

      <div class="row">
        <div class="col-12 main-image-container img-fluid">
          <img src="https://placeholdit.co//i/1280x720?&text=Test">
        </div>
      </div>

      <div class="row pt-1">
        <div class="col-4 col-md-2 mt-2 thumbnail-image-container img-fluid">
          <img src="https://placeholdit.co//i/1280x720?&text=Test">
        </div>
        <div class="col-4 col-md-2 mt-2 thumbnail-image-container img-fluid">
          <img src="https://placeholdit.co//i/1280x720?&text=Test">
        </div>
        <div class="col-4 col-md-2 mt-2 thumbnail-image-container img-fluid">
          <img src="https://placeholdit.co//i/1280x720?&text=Test">
        </div>
        <div class="col-4 col-md-2 mt-2 thumbnail-image-container img-fluid">
          <img src="https://placeholdit.co//i/1280x720?&text=Test">
        </div>
        <div class="col-4 col-md-2 mt-2 thumbnail-image-container img-fluid">
          <img src="https://placeholdit.co//i/1280x720?&text=Test">
        </div>
        <div class="col-4 col-md-2 mt-2 thumbnail-image-container img-fluid">
          <img src="https://placeholdit.co//i/1280x720?&text=Test">
        </div>
      </div>
