Bootstrap 组件上的填充

Question

我正在使用引导程序，但不确定我是否正确使用了列

我似乎无法正确设置边距和填充。

请看下图和JS Fiddle

  <div class="row">
                <!-- MAIN LEFT CONTENT! -->
                <div class="col-lg-9">

                    <div class="panel panel-default">
                         <div class="panel-body">
                            <div class="alert alert-info">
                               <p><span>Pending approval</span>.Your profile is bring approved. This means others can't search for you just yet.</p>
                            </div>
                              <div class="col-lg-5 col-sm-4 col-xs-5 hot-not">
                               <div class="row">
                                  <div class="thumbnail">

Answer 1

规则.col-xs-5（第793行）是固定宽度：

.col-xs-5 {
  width: 41.66666666666667%;
}

将其设置为 50%：

.col-xs-5 {
  width: 50%;
}
