css - Bootstrap 3 嵌套列不是全宽

Question

当我嵌套列时，bootstrap 3 出现问题。嵌套列不是包含列的全宽。它们只有大约三分之二的宽度。在 Bootstrap 中将宽度设置为 33.33%。我尝试了不同的元素。

<section id="content">
  <div class="container">
    <div class="row">
      <div class="col-md-7">
        <h2 class="highlight-prim">Privilage on a card</h2>
        <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>
        <span>See our many partners where your card can used:</span>
        <div class="row">
          <div class="col-md-4">
            <ul class="list-unstyled">
              <li>A1 Driving for life</li>
              <li>A1 Driving for life</li>
              <li>A1 Driving for life</li>
              <li>A1 Driving for life</li>
            </ul>
          </div>
          <div class="col-md-4">
            <ul class="list-unstyled">
              <li>A1 Driving for life</li>
              <li>A1 Driving for life</li>
              <li>A1 Driving for life</li>
              <li>A1 Driving for life</li>
            </ul>
          </div>
          <div class="col-md-4">
            <ul class="list-unstyled">
              <li>A1 Driving for life</li>
              <li>A1 Driving for life</li>
              <li>A1 Driving for life</li>
              <li>A1 Driving for life</li>
            </ul>
          </div>      
        </div>
      </div>
      <div class="col-md-offset-1 col-md-4">
        <h3 class="highlight-sub">Lorem ipsum</h3>
        <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>
      </div>            
      </div>
    </div>
  </div>
</section>

这是未设置填充的屏幕截图。尽管嵌套的列确实变长了，但它们仍然达不到全宽。
