对于Bootstrap 4

Question

我正在使用官方引导程序文档中的代码创建一个简单的复选框：

<div class="custom-control custom-checkbox">
    <input type="checkbox" class="custom-control-input" id="customCheck" name="example1">
    <label class="custom-control-label" for="customCheck">Check this custom checkbox</label>
</div>

我想知道如何使该复选框大于当前的复选框？我尝试编辑customCheck的css并更改height和width属性，但这不会增加框的大小。

Answer 1

我为引导程序开关添加了*-sm, *-md, *-lg, *-xl之类的类。

在这里，我用一个@mixin进行了所有分辨率的切换（@mixin与JS函数非常相似，但它不返回任何内容）。

Answer 2

最好拥有自己的文件，并为开关的尺寸更改css变量：

@import "bootstrap/scss/_functions.scss";
@import "bootstrap/scss/_variables.scss";

$custom-control-indicator-size: 1.5rem;
$custom-switch-width: $custom-control-indicator-size * 1.75;
$custom-switch-indicator-border-radius: $custom-control-indicator-size / 2;
$custom-switch-indicator-size: subtract(
  $custom-control-indicator-size,
  $custom-control-indicator-border-width * 4
);

@import "bootstrap/scss/bootstrap";

Answer 3

此类.custom-switch-adaptive将使开关适应文本大小并在其中包含标签文本。

Demo

P.S。 A similar feature will be added in Bootstrap v5

SCSS

.custom-switch.custom-switch-adaptive {
  padding-left: 0;

  .custom-control-label {
    padding: 0 1.5em;
    position: relative;
    border-radius: 1em;
    line-height: 1.4em;
    color: $text-muted;
    border: 1px solid $text-muted;
    background-color: $light;
    transition: background-color 200ms;

    &::before {
      content: none;
    }
    &::after {
      position: absolute;
      height: 1em;
      top: 0.2em;
      left: 0.2em;
      width: 1em;
      border-radius: 1em;

      transition: left 200ms;
    }
  }


  .custom-control-input:checked ~ .custom-control-label {
    color: $white;
    background-color: $success;
    border-color: $success;

    &::after {
      background-color: $white;
      left: calc(100% - 1.2em);

      transform: none;
      -webkit-transform: none;
    }
  }
}

HTML

<div class="form-group h1">
  <div class="custom-control custom-switch custom-switch-adaptive">
    <input id="test4" type="checkbox" class="custom-control-input">
    <label for="test4" class="custom-control-label">h1 text size</label>
  </div>
</div>

Answer 4

更改引导程序组件尺寸不是一个好主意，您应该更改引导程序中的变量，但这意味着重新编译库。无论如何，您可以通过这种方式完成：

.custom-control-label::before ,.custom-control-label::after{width:20px; height:20px}

Answer 5

我没有足够的声誉来评论Munkh-Erdene Zorigbold。他的答案非常完美。通过添加以下css行，只需覆盖自定义开关的translateX功能即可。这样“打开和关闭”按钮将一直移动到您的新宽度。

.custom-switch .custom-control-input:checked ~ .custom-control-label::after {
  transform: translateX(1.5rem);
}

Answer 6

引导程序 5

我重新设计了 Nisharg Shah 的 css，这样 Text 现在可以很好地与 Bootstrap V5 示例的开关对齐。因此，我查看了 Bootstrap 5 css 源，并增加了所有与大小有关的属性：padding-left、hight、margin-left、width 和 {{1} }. 我认为结果看起来更好，并且与默认的开关外观样式保持一致。

CSS 和 HTML：

padding-top

.form-switch.form-switch-md {
    padding-left: 4.5em;
    height: 2.5em;
}

.form-switch.form-switch-md .form-check-input {
    margin-left: -4.5em;
    height: 2em;
    width: 4em;
}

.form-switch.form-switch-md .form-check-label {
    padding-top: 0.5em;
}

.form-switch.form-switch-lg {
    padding-left: 8.5em;
    height: 4.5em;
}

.form-switch.form-switch-lg .form-check-input {
    margin-left: -8.5em;
    height: 4em;
    width: 8em;
}

.form-switch.form-switch-lg .form-check-label {
    padding-top: 1.5em;
}

Answer 7

由于您正在尝试通过引导程序来完成它，因此它很容易。首先使用btn-group-toggle添加一个div容器以使用组中的按钮（即，如果需要的话）。

在标签中添加p-3或p-5类，以根据您的喜好扩展

<div class="btn-group-toggle" data-toggle="buttons">
        <label class="btn btn-secondary p-3">
            <input type="checkbox" id="customCheck" name="example1"> Check this custom checkbox
        </label>
    </div>

Answer 8

这是使用自定义CSS的有效示例

.custom-checkbox-lg .custom-control-label::before,
.custom-checkbox-lg .custom-control-label::after {
  width: 2rem;
  height: 2rem;
}

.custom-checkbox-lg .custom-control-label {
  margin: .5rem 1rem;
}

您可以尝试以下方式：

.custom-control-label::before, 
.custom-control-label::after {
  width: 2.25rem !important;
  height: 2.25rem !important;
  margin: 1rem;
}
.custom-control-label{
  margin: 1.5rem 2rem;
}

</div>

Answer 10

在引导程序4中，如果您要更改或增加自定义开关（iOS上的漂亮开关），则应深入到引导程序的css文件，并更改其 custom-switch 尺寸的大小 。 html代码如下：

<div class="custom-control custom-checkbox">
 <input type="checkbox" class="custom-control-input" id="switchA" name="switch">
 <label class="custom-control-label" for="switchA">Custom checkbox</label>
</div>

在boostrap.css（4.3.1版且未压缩的版本）文件中，您应该找到 自定义开关 类，并在其中更改以下参数下面。您必须 删除所有我添加的评论 。

.custom-switch {
  padding-left: 2.25rem;
  padding-bottom: 1rem; // added for positioning
}

.custom-control-label { // added for alignment with the switch
  padding-top: 0.5rem;
  padding-left: 2rem;
  padding-bottom: 0.1rem;
}

.custom-switch .custom-control-label::before {
  left: -2.25rem;
  height: 2rem;
  width: 3.5rem;    // it was 1.75rem before. Sliding way is longer than before.
  pointer-events: all;
  border-radius: 1rem;
}

.custom-switch .custom-control-label::after {
  top: calc(0.25rem + 2px);
  left: calc(-2.25rem + 2px);
  width: calc(2rem - 4px);   // it was calc(1rem - 4px) before. Oval is bigger before.
  height: calc(2rem - 4px);  // it was calc(1rem - 4px) before. Oval is bigger than before.
  background-color: #adb5bd;
  border-radius: 2rem; //   it was 0.5rem before. Oval is bigger than before.
  transition: background-color 0.15s ease-in-out, border-color 0.15s ease-in-out, box-shadow 0.15s ease-in-out, -webkit-transform 0.15s ease-in-out;
  transition: transform 0.15s ease-in-out, background-color 0.15s ease-in-out, border-color 0.15s ease-in-out, box-shadow 0.15s ease-in-out;
  transition: transform 0.15s ease-in-out, background-color 0.15s ease-in-out, border-color 0.15s ease-in-out, box-shadow 0.15s ease-in-out, -webkit-transform 0.15s ease-in-out;
}
@media (prefers-reduced-motion: reduce) {
  .custom-switch .custom-control-label::after {
    transition: none;
  }
}

.custom-switch .custom-control-input:checked ~ .custom-control-label::after {
  background-color: #fff;
  -webkit-transform: translateX(1.5rem); //translateX(0.75rem);
  transform: translateX(1.5rem); //translateX(0.75rem);
}

将这些代码复制到Bootstrap文件后，您必须删除所有内容 我输入了评论。否则，它不会增加大小。我希望你喜欢您现在可以进行更大的漂亮切换。
