引导布局问题(Bootstrap layout issues)

具有引导模板工作（无响应模板 - 摄影）。更改照片，颜色的东西我已经和喜欢。开始popovers添加到照片的说明，但现在的布局从3-4消失缩略图宽（span3或span4）对所有照片堆叠垂直。 1列现在代替3或4没有改变任何比其他颜色的CSS。我在哪里出了错？任何想法从哪里得到这个布局纠正？

您正在使用的页面下面的代码多次，将其放置在页脚只有一次。

 <script src="js/jquery.min.js">
 <script src="js/bootstrap-tooltip.js">
 <script src="js/pbootstrap-popover.js">

同时删除了clear div后article tag即

<div class="clear"></div>/*remove*/

我已经清理你的代码了一下，重新安排了一些东西，用在你的身体下面，看看它的预期的结果要达到：
其结果的jsfiddle请检查
