Question

是否可以使col-md-3彼此更接近？这是我的代码：

<!DOCTYPE html>
<html>
  <head>
    <title>Center</title>
<style>

body {
  margin-top: 50px;
}

</style>

  </head>
  <body>

<div class="container">
  <div class="row">
      <div class="col-md-3">
      <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed eleifend imperdiet elit vel pretium. Donec auctor urna ut dui imperdiet ullamcorper.</p>
      </div>
      <div class="col-md-3">
      <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed eleifend imperdiet elit vel pretium. Donec auctor urna ut dui imperdiet ullamcorper.</p>
      </div>
      <div class="col-md-3">
      <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed eleifend imperdiet elit vel pretium. Donec auctor urna ut dui imperdiet ullamcorper.</p>
      </div>
  </div>
</div>
  </body>
</html>

不是中心有没有人知道如何解决它？

非常感谢您的帮助！

Answer 1

是的，可以将css应用于父div。在你的案例div中，class =＆＃34; row＆＃34;喜欢style =＆＃34; text-align：center;＆＃34;

Answer 2

是的，您应该在col-md-offset-3 row中添加class课程，如下所示：

＆＃13;

body {
      margin-top: 50px;
    }

＆＃13;

          </div>
          <div class="col-md-3">
          <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed eleifend imperdiet elit vel pretium. Donec auctor urna ut dui imperdiet ullamcorper.</p>
          </div>
          <div class="col-md-3">

更新HTML

<div class="container">
  <div class="row col-md-offset-1">
      <div class="col-md-3">
      <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed eleifend imperdiet elit vel pretium. Donec auctor urna ut dui imperdiet ullamcorper.</p>
      </div>
      <div class="col-md-3">

      </div>
      <div class="col-md-3">
      <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed eleifend imperdiet elit vel pretium. Donec auctor urna ut dui imperdiet ullamcorper.</p>

是的，但为此你需要覆盖Bootstrap列的样式。默认情况下，Bootstrap的列的样式为float: left。我们需要将float替换为display: inline-block，然后我们可以使用text-align: center轻松将它们置于中心位置。

@import url('https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css');

.center-align .row {
  letter-spacing: -4px;
  text-align: center;
  font-size: 0;
}
.center-align [class*='col-md'] {
  display: inline-block;
  vertical-align: top;
  letter-spacing: 0;
  text-align: left;
  font-size: 16px;
  float: none;
}

<div class="container center-align">
  <div class="row">
    <div class="col-md-3">
      <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed eleifend imperdiet elit vel pretium. Donec auctor urna ut dui imperdiet ullamcorper.</p>
    </div>
    <div class="col-md-3">
      <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed eleifend imperdiet elit vel pretium. Donec auctor urna ut dui imperdiet ullamcorper.</p>
    </div>
    <div class="col-md-3">
      <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed eleifend imperdiet elit vel pretium. Donec auctor urna ut dui imperdiet ullamcorper.</p>
    </div>
  </div>
</div>

注意 ：不要忘记通过制作元素inline-block来删除额外的空间。
