  • Center a column using Twitter Bootstrap 3 28 answers

    • Yes, but for this you need to override styling for Bootstrap's columns. By default Bootstrap's columns are styled as float: left . We need to replace float with display: inline-block then we can make them in center easily with text-align: center . 

    @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>

    Yes it is possible, to apply css to parent div. In your case div with class="row" like style="text-align:center;"

    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">
      <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>
