响应网格中的空列

Question

我有点进退两难。首先，这是一个[codepen] [1]。我的问题是，我有一个4列网格结构，左栏保留给副标题，内容出现在其他3列。

我有一个名为＆＃39; social＆＃39;的部分，我希望在3列中每列显示1个个人资料图片。问题是，当我添加一行新图像时，它们从左列（为子标题保留的列）开始。有没有办法通过添加空列来阻止这种情况？我尝试使用＆amp; nbsp但似乎只是弄乱了我的格式。

另一个问题是，当网站变得移动时，我希望图像显示为2行。添加空白列后，这将如何影响它们随后在移动设备中的布局？会有空白吗？

很抱歉，如果这令人困惑。我对这一切还是比较新的。谢谢你的帮助！

Answer 1

这是一个CSS片段，可以帮到你！

.image-item:nth-child(5n) {
   margin-left:25%;
 }

这里发生的是每第4个图像项目，我们正在添加一个“额外”图像项左边缘，以创建一个错觉，即您的社交列是图像网格其余部分的单独实体。 / p>

无需您尝试插入并清空列

Answer 2

像这样添加空列：

$First_date = date_create('this week')->format('Y-m-d H:i:s');
$Last_date = date_create('this week +4 days')->format('Y-m-d H:i:s');
echo $First_date;
echo $Last_date;

问题一：

<div class="grid-item empty">
 &nbsp;
</div>

提问二 ......

.empty {
  clear: both;
}

有关clear财产的信息。
