Question

我有一个复选框

<div class="custom-control custom-checkbox custom-control-inline">
   <input type="checkbox"  id="location"  v-model="checkedLocations"   value="location" name="customRadioInline1" class="custom-control-input">
   <label class="custom-control-label" for="location"> Option 1</label>
</div>

如何移动标签以显示在左侧？我已经尝试过更改顺序，但这只会破坏复选框的功能。

    <div class="custom-control custom-checkbox custom-control-inline">
         <label class="custom-control-label" for="location2"> Option 2</label>
        <input type="checkbox"  id="location2"  value="location2" name="custom2" class="custom-control-input">
   </div>

Answer 1

此复选框不是实际的<input>（已隐藏）。这样做是为了始终如一地跨浏览器和跨设备设置其样式，因为<input type="checkbox">当前无法实现。

相反，使用::before的{{1}}伪元素。

因此，您应该在包装器上放置一个自定义类（在下面的示例中为<label>），并添加一些覆盖默认值的CSS：

custom-control-right

div.custom-control-right {
  padding-right: 24px;
  padding-left: 0;
  margin-left: 16px;
  margin-right: 0;
}
div.custom-control-right .custom-control-label::before,
div.custom-control-right .custom-control-label::after{
  right: -1.5rem;
  left: initial;
}

注意：如果在加载Bootstrap CSS之后解析了此代码，则可以将<link href="https://cdnjs.cloudflare.com/ajax/libs/twitter-bootstrap/4.1.3/css/bootstrap.min.css" rel="stylesheet"/> <div style="margin:20px;"> <div class="custom-control custom-checkbox custom-control-inline custom-control-right"> <input type="checkbox" id="location" value="location" name="custom1" class="custom-control-input"> <label class="custom-control-label" for="location"> Option 1</label> </div> <div class="custom-control custom-checkbox custom-control-inline custom-control-right"> <input type="checkbox" id="location2" value="location2" name="custom2" class="custom-control-input"> <label class="custom-control-label" for="location2"> Option 2</label> </div> </div>选择器替换为div.custom-control-right。但是，在SO上，链接资源是在CSS面板中的代码之后加载的，为了使它起作用，我不得不对选择器进行过分限定。

尝试：Fiddle

<div style="margin:20px;">
  <div class="custom-control custom-checkbox custom-control-inline">
    <input type="checkbox" id="location" value="location" name="custom1" class="custom-control-input">
    <label class="custom-control-label" for="location"> Option 1</label>
  </div>

  <div class="custom-control custom-checkbox custom-control-inline">

    <input type="checkbox" id="location2" value="location2" name="custom2" class="custom-control-input">
    <label class="custom-control-label" for="location2"> Option 2</label>
  </div>
</div>

css：

.custom-checkbox {
  padding-left: 0;
}

label.custom-control-label {
  padding-right: 1.5rem;
}

.custom-control-label::before,
.custom-control-label::after {
  right: 0;
  left: auto;
}

Answer 3

答案似乎不适用于custom-switch。这是一个可行的示例。

CSS

div.custom-control-right {
    padding-right: 24px;
    padding-left: 0;
    margin-left: 0;
    margin-right: 0;
}
div.custom-control-right .custom-control-label::after{
    right: -1.5rem;
    left: auto;
}
div.custom-control-right .custom-control-label::before {
    right: -2.35rem;
    left: auto;
}

HTML

<div class="custom-control custom-control-right custom-switch">
    <input type="checkbox" class="custom-control-input" disabled id="customSwitch2">
    <label class="custom-control-label" for="customSwitch2">Right switch element</label>
</div>

编辑：将left:initial更改为left:auto以使其与IE11兼容。
