如何在移动设备上解决Bootstrap网格问题？

Question

我正在编辑Ebay列表中的说明，其中不允许编写脚本。 ebay描述嵌入在ebay模板中。

我发现我的#portfolio无法在mobile上正确显示！

在desktop上它完全正常，因为它们是col-lg-3。在移动ive使用col-xs-6，因为我想要一个2 x 2网格。 问题是最后一列被拖入另一行。 请参阅上面显示我的问题的移动图片。

有人能够教我一个新的CSS技巧，阻止最后一栏被吸进新行吗？

CSS：

/*Portfolio items*/


    #portfolio .portfolio-item {
        margin: 0 0 15px;
        right: 0;
        border: 1px outset rgba(255, 255, 255, 0.6);

    #portfolio .portfolio-item .portfolio-link {
        display: block;
        position: relative;
        max-width: 400px;
        margin: 0 auto;

Answer 1

防止对象跳跃您需要使用clearfix仅对xs视口可见。 它看起来像：

    <div class="clearfix visible-xs-block"></div>

所以这是一个结果代码：

<div id="portfolio" class="container-fluid text-center ">
    <h2><font color="#ce2065">the shills black mask</font><br><font size="1">&nbsp;</font></h2>
    <div class="row">
        <div class="col-sm-3 col-xs-6"> <img src="http://justbeauty-uk.s3.amazonaws.com/shillspoint1.jpg" class="img-responsive img-thumbnail img-circle margin" alt="Image" style="text-align: center; width: 60%;">
            <p style="text-align: center;"><span style="line-height: 1.8;">The latest trend in skincare.&nbsp;</span>Proven results with the word’s best selling black mask - loved by beauty bloggers, as seen on YouTube</p>
        </div>
        <div class="col-sm-3 col-xs-6"> <img src="http://justbeauty-uk.s3.amazonaws.com/shillspoint2.jpg" class="img-responsive img-thumbnail img-circle margin" alt="Image" style="text-align: center; width: 60%;">
            <p><span style="line-height: 1.8;">Activated charcoal quickly and effectively pulls blackheads from the root and aids skin regeneration. Promotes healthy skin too!</span></p>
        </div>
        <div class="clearfix visible-xs-block"></div>
        <div class="col-sm-3 col-xs-6"> <img src="http://justbeauty-uk.s3.amazonaws.com/shillspoint3.jpg" class="img-responsive img-thumbnail img-circle margin" style="text-align: center; width: 60%;">
