我在很多地方都发现了这个问题(例如:Bootstrap: Dyamic columns with container-fluid and row not wrapping properly)，每次都是在一些尺寸的屏幕将被包裹的位置添加一个 clearfix div ，但我已经在这样做了。
<div class="container">
<div class="row">
<div class="col-xs-4 col-md-2">
<img class="img-responsive center-block bottom10" src="/assets/filetypes/pdf.png" alt="Pdf">
</div>
<div class="col-xs-4 col-md-2">
<img class="img-responsive center-block bottom10" src="/assets/filetypes/doc.png" alt="Doc">
</div>
<div class="col-xs-4 col-md-2">
<img class="img-responsive center-block bottom10" src="/assets/filetypes/html.png" alt="Html">
</div>
<div class="clearfix visible-xs-block"></div>
<div class="col-xs-4 col-md-2">
<img class="img-responsive center-block bottom10" src="/assets/filetypes/mp3.png" alt="Mp3">
</div>
<div class="col-xs-4 col-md-2">
<img class="img-responsive center-block bottom10" src="/assets/filetypes/mov.png" alt="Mov">
</div>
<div class="col-xs-4 col-md-2">
<img class="img-responsive center-block bottom10" src="/assets/filetypes/ppt.png" alt="Ppt">
</div>
</div>
</div>
最佳答案
丹，您好。很明显，clearfix 在这里没有帮助您，因为第 3 个图像的高度小了 1px。
因此，如果不使所有图像大小相同，要解决此问题，只需使用 2 行。
每行包含 3 张图像。
此代码可满足您的需要。
