Boostrap拉右导致元素重叠 [英] Boostrap pull-right causing element overlap

问题描述

当我将一个右键类添加到按钮上时， （或包含div），则按钮被列表重叠。

 < div> 
< div class =pull-right> 
< button type =buttonclass =btn btn-default>添加< / button> 
< / div> 
< ul class =list-group> 
< li class =list-group-item>有点东西1< / li> 
< li class =list-group-item>有点东西2< / li> 
< li class =list-group-item>有点东西2< / li> 
< / ul> 
< / div>

解决方案

您应该添加 pull-right 类改为按钮元素，然后向父元素添加一个clearfix。这样， div 将不会自行折叠。

更新示例

 < div class = clearfix> 
< button type =buttonclass =btn btn-default pull-right>添加< / button> 
< / div> 
  

---

或者，由于按钮是 inline-block 级别元素，可以避免浮动，并使用 text-align：right 。只需将类 text-right 添加到父级。您不再需要clearfix，因为按钮元素未从文档流中删除。

这里的例子

 < button type =buttonclass =btn btn-default>添加< / button> 
< / div> 
  

I am trying to get a single button positioned above a list, but with the button to the right.

When I add the pull-right class to the button (or a containing div) the button is then overlapped by the list.

<div>
    <div class="pull-right">
        <button type="button" class="btn btn-default">Add</button>
    </div>
    <ul class="list-group">
        <li class="list-group-item">Something something 1</li>
        <li class="list-group-item">Something something 2</li>
        <li class="list-group-item">Something something 2</li>
    </ul>
</div>

解决方案

You should add the pull-right class to the button element instead and then add a clearfix to the parent element. In doing so, the div won't collapse upon itself.

Updated Example

<div class="clearfix">
    <button type="button" class="btn btn-default pull-right">Add</button>
</div>

---

Alternatively, since the button is an inline-block level element, you could avoid floating it and use text-align:right instead. Just add the class text-right to the parent. You no longer need the clearfix because the button element isn't being removed from the document flow.

Example Here

<div class="text-right">
    <button type="button" class="btn btn-default">Add</button>
</div>
