Question

我明确了父元素，但我不知道如何解决这类问题，因为我从某个容器中扣除了lorem lpsum的长度并且它错位了。

＆＃13;

display_errors = on

Answer 1

clear是与浮点数相关的CSS属性。主要是关于前面的花车 clearfix是一个概念，用于包含（降序）浮点数。见SO answers about What is clearfix?

2015年不需要JS来做到这一点！使用.clear的HTML解决方案很好，除非你有很多断点和需要管理的情况。然后你需要不同的类，例如.small-clear，.large-clear.clear，等等，其中前缀用作提醒他们应该应用哪个断点。

以下是纯CSS中的3个解决方案：

使用CSS3 :nth-child(an+b)（兼容性：IE9 +）每4个项目添加clear: left：

现在是display: inline-block解决方案，vertical-align: top代替默认基线（非常适合文字和内容，不适用于布局;））。
兼容性至少是IE8 +（对于一些黑客而言更少，但谁更关心？）：

Answer 2

当我遇到这些问题时，我会使用它来添加到html＆＃34;清除＆＃34; div`s。在你的情况下，我将包括每4个元素：

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

clear班级只有：

.clear {clear:both;}

您可能希望在不使用固定宽度的情况下进行网络响应，因此您甚至可以在div's和display:none的元素之间添加更多clear来制作它们＃34;有形项目＆＃34;到达视口宽度时。

作为示例，我添加了第二个div，如：

<div class="clear2"></div>

每两个元素都带有这些css：

.clear2 {clear:both; display:none;}

@media only screen and (max-width: 650px) {
    .container section .wcon {width:47%;} /*        
    .clear2 {display:block;}          
    }

（47％只是每行2个元素的快速方法）

编辑：另一个方法是计算（如果文本看起来像dinamic）最高元素的最大高度，并将该高度应用于所有元素。用这个jquery：

$(document).ready(function() {
   var maxHeight = -1;

   $('.wcon').each(function() {
     maxHeight = maxHeight > $(this).height() ? maxHeight : $(this).height();
   });

   $('.wcon').each(function() {
     $(this).height(maxHeight);
   });
 });
