twitter-bootstrap – 在Bootstrap 3.0中遇到img-circle圆形图像问题

我正在使用Bootstrap 3.0.我想用“img-circle”类显示三个图像.如何摆脱这些图像周围的子弹点和框?

谢谢

<div class="row">
    <ul class="thumbnails">
            <li class="col-md-4">
                    <article class="thumbnail">
                    <img src="img/content writing.jpg" alt="pencil" class="img-circle">
                    <h3>Content Writing</h3>
                    <p>lore ipsum</p>
                </article>
            </li>
            <li class="col-md-4">
                <article class="thumbnail">
                <img src="img/design.jpg" alt="folder" class="img-circle">
                <h3>Design</h3>
                <p>lore ipsum</p>
                </article>
             </li>
            <li class="col-md-4">
                <article class="thumbnail">
                    <img src="img/social media.jpg" alt="person" class="img-circle">
                    <h3>Social Media</h3>
                    <p>lore ipsum</p>
                </article>
            </li>
    </ul>
 </div>

最佳答案 在Bootstrap 3中,缩略图不再需要包含在ul.thumbnails中.比较
example code in the Bootstrap 2.3 documentation
Bootstrap 3(摘录如下):

<div class="row">
  <div class="col-sm-6 col-md-3">
    <a href="#" class="thumbnail">
      <img data-src="holder.js/100%x180" alt="...">
    </a>
  </div>
  ...
</div>

删除ul将摆脱要点.
