Bootstrap aligment问题

Question

我试图将一些元素与bootstrap对齐，但我们之间存在着奇怪的差距。我可以问你一些建议吗？ 这是布局结构的最终图片。

这是我的代码，直到现在

Answer 1

假设我理解正确，你的html太多了。绝对没有必要将单个图像包装到列表中。

全屏查看，我没有添加小型显示类。

.margin{margin-bottom: 25px;}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />
   
<section class="product-list">
  <div class="container">
    <div class="row">
      <div class="col-md-6">
        <div class="row margin">
      <div class="col-md-6">
              <a href="#">
                <img src="https://s23.postimg.org/mjrt9w557/example.jpg" width="260" height="260" title="someText" alt="someText">
              </a>
      </div>
      <div class="col-md-6">
              <a href="#">
                <img src="https://s23.postimg.org/mjrt9w557/example.jpg" width="260" height="260" title="someText" alt="someText">

      <div class="col-md-6">

Answer 2

如果我理解你的问题是正确的，你会想知道这些元素之间的差距。 Bootstrap在名为 gutter 的列之间应用填充。如果您不希望列之间存在间隙，则可能需要调整装订线边距和边距。

Answer 3

使用两个col-md-6并在第一个col-md-6内部使用具有特定高度的4 col-md-6，您的问题就解决了。
