我需要将中心(中间)对齐一个复选框。这是我的代码:
<div class="col-xs-4"><input type="checkbox" id="{gruppi.nome_gruppo}" style="vertical-align:middle"></div>
但它不起作用。有人可以帮帮我吗?

添加col-xs-offset-4
和text-center
以使其位于中心
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>
<div class="col-xs-4 col-xs-offset-4 text-center"><input type="checkbox" id="{gruppi.nome_gruppo}" style="vertical-align:middle"></div>
&#13;
或使用col-xs-12
和text-center
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>
<div class="col-xs-12 text-center"><input type="checkbox" id="{gruppi.nome_gruppo}" style="vertical-align:middle"></div>
&#13;
如果您还想垂直对齐
.outer-class{
width:100px;
height:100px;
background-color:#ccc;
}
.inner-class{
line-height:100px;
}
&#13;
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>
<div class="outer-class">
<div class="inner-class text-center"><input type="checkbox" id="{gruppi.nome_gruppo}" style="vertical-align:middle"></div>
</div>
&#13;
另一个例子
.outer{
width:100%;
height:100px;
background-color:#ccc;
}
.inner{
width:50%;
height:50%;
background-color:#808080;
}
.make-center{
display: flex;
justify-content: center;
align-items: center;
}
&#13;
<div class="outer make-center">
<div class="inner make-center">
<input type="checkbox" id="{gruppi.nome_gruppo}" style="vertical-align:middle;height:40px">
</div>
</div>
&#13;
我假设你正在使用这个类col-xs-4
使用bootstrap

你可以试试这个:
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta/css/bootstrap.min.css" integrity="sha384-/Y6pD6FV/Vv2HJnA6t+vslU6fwYXjCFtcEpHbNJ0lyAFsXTsjBbfaDjzALeQsN6M" crossorigin="anonymous">
<div class="col-xs-4 text-center">

你好你可以通过在复选框中设置高度来获得它 检查一下
.bg{
background:#e2e2e2;}
<!-- Latest compiled and minified CSS -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<div class="col-xs-4 bg"><input type="checkbox" id="{gruppi.nome_gruppo}" style="vertical-align:middle;height:40px"></div>
