将div彼此堆叠

[英]Stack divs ontop of each other

我目前有一个样式为表格的三列div集。

我希望将这三列垂直堆叠在移动设备上。

我相信使用float方法可以做到这一点,但是每列的标题和描述都出现在单独的行(divs)中,所以我不确定如何实现此目的?

我必须为单元格设置显式宽度,以便适当调整它们的大小。 您可以删除行并进行必要的更改以具有相同的样式。
我用了

width: 250px

使用弹性框和媒体查询:

  • 使用flexbox在行方向开始布局,请参见第15行。
  • 3列每个元素只能包含几个元素,无需为所有内容都设置div。 使用边距,内边距和边框可见地定义结构。
  • 使用媒体查询触发布局更改。 在此示例中,如果屏幕的宽度为600px或更小,则flexbox属性将变为以列的形式流动,请参见第25行。

在整页模式下查看代码段,并调整大小以使flexbox发挥作用。

您使用div的方式似乎无法获得您想要的。 这是下面的代码

 .container{ padding:0; padding:0; } .box{ margin:0; padding:0 .5em 0; width:30%; float:left; } .box h3{ margin:0; padding:0; } .box div{ border-right:2px dotted #ccc; min-height:200px } @media(max-width:598px){ .box{ width:100%; } .box div{ border-bottom:2px dotted #ccc; min-height:0px; } } 
 <div class="container"> <div class="box"> <h3>New to Workbooks?</h3> <div> <p>Using Workbooks for the first time?</p> </div> </div> <div class="box"> <h3>Training videos</h3> <div> <p>Watch our short training videos to find out how to use Workbooks:</p> </div> </div> <div class="box"> <h3>System Admin</h3> <div> <p> System Administrator? Familiarise yourself with the following:</p></div> </div> </div> 

尝试更改响应式设计的浏览器大小。

您可以使用CSS媒体查询轻松地做到这一点。 这个想法是针对所有可能没有大屏幕且不支持css3(在您的情况下为垂直堆叠)的设备保留标准设计,而另一种设计是将它们水平堆叠以支持css3的更大屏幕。 许多网站都采用类似的方法。 无论您的用户使用什么设备,都将始终处于安全状态:

它的工作方式如下: CSS

 .container {
    width:1200px;
    margin: 0px auto;
}
    .leftDiv {
        background-color:blue;
         width: 400px;
         height:200px;
    }
    .rightDiv {
        background-color:green;
         width: 400px;
         height:200px;
    }
    .centreDiv {
         width: 400px;
         height:200px;
         background-color: yellow;
     }



        @media only screen and (min-width:883px) {

    .leftDiv {
        float:left;
    }

        .centreDiv {
            float:left;

    }
    .rightDiv {
        float:right;
    }

    }

html

<div class="container">
<div class="leftDiv" >Left</div>
<div class="centreDiv">Centre</div>
<div class="rightDiv">Right</div></div>

对于此用途,可以使用Bootstrap。 Bootstrap允许您使用行/列布局轻松,动态地设置页面样式。 请访问Bootstrap网站获取更多信息。 您想要的是一种行布局,该布局将自动叠加到移动设备上。 请参阅此小提琴作为示例

<div class="row">
  <div class="col-md-4">
    <h2>
New to workbooks?
</h2>
    <br />
    <p>
      Using workbooks for the first time?
    </p>
    <ul>
      <li>link 1</li>
      <li>link 3</li>
      <li>link 2</li>
    </ul>

  </div>
  <div class="col-md-4">
    <h2>
System Admin
</h2>
    <br />
    <p>
      Familiarise yourself
    </p>
    <ul>
      <li>link 1</li>
      <li>link 3</li>
      <li>link 2</li>
    </ul>
  </div>
  <div class="col-md-4">
    <h2>Training videos</h2>
    <br />
    <p>Watch out short videos</p>
    <ul>
      <li>link 1</li>
      <li>link 3</li>
      <li>link 2</li>
    </ul>
  </div>
</div>

这可能对您来说不是最好的方法,但它会起作用。

       width:30%;
      padding: 3px 10px;
      height:200px;
    } 

您不需要像表一样使div动作。 您可以使用float并排显示它们。 使用最小宽度,您可以确保在达到最小值时它们会互相压住。 我也给出了高度值,因为如果div左移,并且div的高度比中间的div高,那么div在彼此下方时,右侧的div就会卡在中间的div之下。 我不知道我能否表达自己的意思,但希望这一点对您有用:)
