从 Bootstrap 3 中的缩略图中删除烦人的白色背景

Question

我创建了一小段代码，它在一行中以相等的网格宽度显示了 4 个缩略图。

.row-content-3 {
    background-color: rgba(0,0,0,0.8) !important;
    color: #fff;
    margin:0px auto;
    padding: 50px 0px 50px 0px;
    min-height:200px;
}

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>
<div class="row row-content-3">
        <div class="col-xs-12 col-sm-3 col-md-3 col-lg-3">
            <div class="thumbnail">
               <a href="#">
                 <img src="http://www.theo-android.co.uk/github-images/fair1.png" class="img-circle" alt="Larissa's fair"> 
               </a>
            </div>
        </div>
        <div class="col-xs-12 col-sm-3 col-md-3 col-lg-3">
            <div class="thumbnail">
               <a href="#">
                 <img src="http://www.theo-android.co.uk/github-images/fair2.png" class="img-circle" alt="Larissa's fair"> 
               </a>
            </div>
        </div>
        <div class="col-xs-12 col-sm-3 col-md-3 col-lg-3">
            <div class="thumbnail">
               <a href="#">
                 <img src="http://www.theo-android.co.uk/github-images/fair3.png" class="img-circle" alt="Larissa's fair"> 
               </a>
            </div>
        </div>
        <div class="col-xs-12 col-sm-3 col-md-3 col-lg-3">
            <div class="thumbnail">
               <a href="#">
                 <img src="http://www.theo-android.co.uk/github-images/fair4.png" class="img-circle" alt="Larissa's fair"> 
               </a>
            </div>
        </div>   
 </div>

如果您运行代码，您会注意到有一个白色背景需要删除。我把这个 css 简单的代码，但它没有工作:(.

.thumbnail {
  border: 0;
}

我也给你jsfiddle。

任何想法，

谢谢西奥。

Answer 4

设置以下样式应该可以做到：

.thumbnail {
    background-color: transparent;
    border: none;
}

Answer 5

如果我没记错的话，那么你只想从圆形图像中移除白色背景。

我添加了这个

.thumbnail {
  border: 0;
  background: transparent;
}

而且你可以看到还有方框阴影。您可以使用

删除它

box-shadow: none;
