Bootstrap Affix问题：添加最高保证金

Question

我在data-offset-top="360"之后启用了一个Affix侧边栏，但事实是当启用Affix时，该侧边栏不会保留它并且它会获得一个上边距。

以下是我正在使用的代码：

<div class="col-md-4" class="page-sidebar">
                <div data-spy="affix" data-offset-top="360" data-offset-bottom="0">
                <ul class="nav nav-pills nav-stacked nav-categories">
                  <li role="presentation"><a href="#">Telefoane Mobile, Tablete si Laptopuri <span class="badge">0</span></a></li>
                  <li role="presentation"><a href="#">PC, Componente si Periferice <span class="badge">0</span></a></li>

                </ul>
                </div>
            </div>
