css - 修复了 body-content 宽度为 100% 的 div

Question

我正在使用 Bootstrap 并试图将一个 div 修复到 body-container div 的顶部。
使用此 css，我能够将 div 固定到容器的顶部，但它溢出了 body-container div 的右侧:

.top-bar {
    position: fixed;
    z-index: 1030;
    top: 60px;
    width: 100%;
}
.top-bar .item-count h4{   
    text-align: center;
}

这是我所有的 html/css:https://jsfiddle.net/rttvqa3k/

旧:

<div class="top-bar panel panel-default">
    <div class="panel-body row">
        <div class="col-xs-4 col-sm-4 col-md-4">
            <button class="btn btn-default">Button 1</button>
            <button class="btn btn-default">Button 2</button>
        </div>
        <div class="col-xs-4 col-sm-4 col-md-4 matter-count">
            <h4>### Items in Report</h4>
        </div>
        <div class="col-xs-4 col-sm-4 col-md-4">
            <button class="btn btn-default pull-right">Button 3</button>
        </div>
    </div>
</div>

新:

<div class="navbar-fixed-top container" style="top:60px;">    
    <div class="panel panel-default">

    <div class="panel-body row">
        <div class="col-xs-4 col-sm-4 col-md-4">
            <button class="btn btn-default">Button 1</button>
            <button class="btn btn-default">Button 2</button>
        </div>
        <div class="col-xs-4 col-sm-4 col-md-4 matter-count">
            <h4>### Items in Report</h4>
        </div>
        <div class="col-xs-4 col-sm-4 col-md-4">
            <button class="btn btn-default pull-right">Button 3</button>
        </div>
    </div>
      </div>
