Javascript 如何使用引导将iframe嵌入整个窗口（不要与全屏混淆）？

我正在将链接嵌入iframe：

<div class="container hidden" id="timeline" style="position: relative;">
    <div class="embed-responsive embed-responsive-16by9">
            <iframe allowfullscreen="true" class="embed-responsive-item container well well-small span6" frameborder="0" id="timeline_view" mozallowfullscreen="true" msallowfullscreen="true" oallowfullscreen="true" src="" webkitallowfullscreen="true">
            </iframe>
    </div>
</div>

它没有占据整个窗户。但它占据了一个小矩形。我尝试了其他选择：

这对我很有用：

    <!-- Timeline Viewer -->
    <div class="container hidden" id="timeline">
        <iframe style="position:absolute;top:0;left:0;width:100%;height:100%" allowfullscreen="true" frameborder="0" id="timeline_view" mozallowfullscreen="true" msallowfullscreen="true" oallowfullscreen="true" src="" webkitallowfullscreen="true">
        </iframe>
    </div>

    <!-- Timeline Viewer -->
    <div class="container hidden" id="timeline">
        <iframe style="position:absolute;top:0;left:0;width:100%;height:100%" allowfullscreen="true" frameborder="0" id="timeline_view" mozallowfullscreen="true" msallowfullscreen="true" oallowfullscreen="true" src="" webkitallowfullscreen="true">
        </iframe>
    </div>
