我浪费了很多时间来搜索输入和输入组的自己的xs大小(小于小), 所以这是代码!

以下是他们的回复:

我们不会将它添加到v3中,我认为即使在v4中我们也不会有xs按钮,但如果我们选择保留它,我会记住它.

Answer 1

对于输入smallers:

.input-xs {
  height: 22px;
  padding: 2px 5px;
  font-size: 12px;
  line-height: 1.5; /* If Placeholder of the input is moved up, rem/modify this. */
  border-radius: 3px;
}

输入组中的示例用法:

<div class="input-group">
    <span class="input-group-btn">
        <button class="btn btn-xs btn-success">
            <i class="glyphicon glyphicon-plus"></i>
        </button>
    </span>
    <input type="text" class="form-control input-xs" />
    <span class="input-group-btn">
        <button class="btn btn-xs btn-danger">
            <i class="glyphicon glyphicon-minus"></i>
        </button>
    </span>
</div>

或者,您可以像这样添加类到输入组:

.input-group-xs>.form-control,
.input-group-xs>.input-group-addon,
.input-group-xs>.input-group-btn>.btn {
    height: 22px;
    padding: 1px 5px;
    font-size: 12px;
    line-height: 1.5;
}

并使用:

<div class="input-group input-group-xs">
    <span class="input-group-btn">
        <button class="btn btn-success">
            <i class="glyphicon glyphicon-plus"></i>
        </button>
    </span>
    <input type="text" class="form-control" />
    <span class="input-group-btn">
        <button class="btn btn-danger">
            <i class="glyphicon glyphicon-minus"></i>
        </button>
    </span>
</div>

.input-xs {
  height: 22px!important;
  padding: 2px 5px;
  font-size: 12px;
  line-height: 1.5;
  border-radius: 3px;
}
.input-group-xs>.form-control,
.input-group-xs>.input-group-addon,
.input-group-xs>.input-group-btn>.btn {
  height: 22px;
  padding: 1px 5px;
  font-size: 12px;
  line-height: 1.5;
}

      <i class="glyphicon glyphicon-plus"></i>
    </button>
  </span>
  <input type="text" class="form-control input-xs" />
  <span class="input-group-btn">
    <button class="btn btn-xs btn-danger">
      <i class="glyphicon glyphicon-minus"></i>
    </button>
  </span>
</div>
<br/>
<div class="input-group input-group-xs">
  <span class="input-group-btn">
    <button class="btn btn-success">
      <i class="glyphicon glyphicon-plus"></i>
    </button>
  </span>
  <input type="text" class="form-control" />
  <span class="input-group-btn">
    <button class="btn btn-danger">
      <i class="glyphicon glyphicon-minus"></i>
    </button>
  </span>
</div>

Answer 2

如果您使用bootstrap-sass，则可以利用input-sizemixin：

$input-height-xs: 27px; // adjust it according to your theme.

@include input-size('.input-xs', $input-height-xs, $padding-xs-vertical, $padding-xs-horizontal, $font-size-small, $line-height-small, $input-border-radius-small);
