將跨度元素與表格中的td對齊

Question

如何使跨度元素與表格列中的排序方式一致？ 即如何使step，glyphicons和X對齊同表 （如：glyphicons向上移動，如果我們使用跨度）

的Html

<div class="row moving"> 
<div class="col-md-12"> 
    <span class="col-md-1"><h4>Step</h4></span> 
    <span class="col-md-8"><textarea class="form-control"></textarea></span> 
    <span class="col-md-1"><span class="glyphicon glyphicon-circle-arrow-up"></span></span> 
    <span class="col-md-1"><span class="glyphicon glyphicon-circle-arrow-down"></span></span> 
     <span class="col-md-1"><span>X</span></span> 
</div> 
    </div> 

</br> 
<table> 
    <tr> 
     <td class="col-md-1"><h4>Step</h4></td> 
     <td class="col-md-8"><textarea class="form-control"></textarea></td> 
     <td class="col-md-1"><span class="glyphicon glyphicon-circle-arrow-down"></span></td> 
     <td class="col-md-1"><span class="glyphicon glyphicon-circle-arrow-up"></span></td> 
     <td class="col-md-1"><span>X</span></td> 
    </tr> 
</table> 

CSS

.moving{ 
    margin-top:10px; 
} 
textarea{ 
    resize:none; 
} 

這是一個fiddle

Answer 1

您可以使用CSS3靈活盒子進行對齊。 align-items: center將使柔性盒子容器內的元件對齊在橫軸（垂直平面）的中心。

JSfiddle demo

.moving { 
 
    margin-top: 10px; 
 
} 
 
textarea { 
 
    resize: none; 
 
} 
 
.moving .centered-vertically { 
 
    display: flex; 
 
    align-items: center; 
 
}

    <tr> 
 
    <td class="col-md-1"> 
 
     <h4>Step</h4> 
 

 
    </td> 
 
    <td class="col-md-8"> 
 
     <textarea class="form-control"></textarea> 
 
    </td> 
 
    <td class="col-md-1"><span class="glyphicon glyphicon-circle-arrow-down"></span> 
 

 
    </td> 
 
    <td class="col-md-1"><span class="glyphicon glyphicon-circle-arrow-up"></span> 
 

 
    </td> 
 
    <td class="col-md-1"><span>X</span>
