自定义 Bootstrap 复选框

Question

我在我的 Angular 应用程序中使用 Bootstrap，所有其他样式都可以正常工作，但复选框样式却没有。它看起来就像普通的旧复选框。

 <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">
<div class="container">
  <form class="form-signin">
    <h2 class="form-signin-heading">Please log in</h2>
    <label for="inputEmail" class="sr-only">User name</label>
    <input [(ngModel)]="loginUser.Username" type="username" name="username" id="inputEmail" class="form-control" placeholder="User name" required autofocus>
    <label for="inputPassword" class="sr-only">Password</label>
    <input [(ngModel)]="loginUser.Password" type="password" name="password" id="inputPassword" class="form-control" placeholder="Password" required>
    <a *ngIf="register == false" (click)="registerState()">Register</a>
    <div class="checkbox">
      <label>
         <input type="checkbox" [(ngModel)]="rememberMe" name="rememberme"> Remember me
         </label>
    </div>
    <button *ngIf="register == false" (click)="login()" class="btn btn-lg btn-primary btn-block" type="submit">Log in</button>
  </form>
</div>

它看起来像什么：

我希望它看起来像 Bootstrap 风格：

由于 Bootstrap 3 没有 复选框 样式，因此我发现 了一个非常适合 Bootstrap 样式的定制。

复选框

 .checkbox label:after {
  content: '';
  display: table;
  clear: both;
}

.checkbox .cr {
  position: relative;
  display: inline-block;
  border: 1px solid #a9a9a9;
  border-radius: .25em;
  width: 1.3em;
  height: 1.3em;
  float: left;
  margin-right: .5em;
}

.checkbox .cr .cr-icon {
  position: absolute;
  font-size: .8em;
  line-height: 0;
  top: 50%;
  left: 15%;
}

.checkbox label input[type="checkbox"] {
  display: none;
}

.checkbox label input[type="checkbox"]+.cr>.cr-icon {
  opacity: 0;
}

.checkbox label input[type="checkbox"]:checked+.cr>.cr-icon {
  opacity: 1;
}

.checkbox label input[type="checkbox"]:disabled+.cr {
  opacity: .5;
}

</div>

<!-- Checked checkbox -->
<div class="checkbox">

   <input type="checkbox" value="" checked>
   <span class="cr"><i class="cr-icon glyphicon glyphicon-ok"></i></span>
   Option two is checked by default

</div>

<!-- Disabled checkbox -->
<div class="checkbox disabled">

   <input type="checkbox" value="" disabled>
   <span class="cr"><i class="cr-icon glyphicon glyphicon-ok"></i></span>
   Option three is disabled
   </label>
</div>

收音机

 .checkbox label:after,
.radio label:after {
  content: '';
  display: table;
  clear: both;
}

.checkbox .cr,
.radio .cr {
  position: relative;

.checkbox .cr .cr-icon,
.radio .cr .cr-icon {

  font-size: .8em;
  line-height: 0;
  top: 50%;
  left: 13%;
}

.radio .cr .cr-icon {
  margin-left: 0.04em;
}

.checkbox label input[type="checkbox"],

   </label>

自定义图标

您可以通过将 [icon name] 更改为您的图标，在 Bootstrap 或 Font Awesome 中选择您自己的图标。

 <span class="cr"><i class="cr-icon [icon name]"></i>

例如：

• glyphicon glyphicon-remove 用于引导程序，或
• fa fa-bullseye 字体真棒

 .checkbox label:after,
.radio label:after {
  content: '';
  display: table;
  clear: both;
}

.checkbox .cr,
.radio .cr {
  position: relative;
  display: inline-block;
  border: 1px solid #a9a9a9;
  border-radius: .25em;
  width: 1.3em;
  height: 1.3em;
  float: left;
  margin-right: .5em;
}

.radio .cr {
  border-radius: 50%;
}

.checkbox .cr .cr-icon,
.radio .cr .cr-icon {
  position: absolute;
  font-size: .8em;
  line-height: 0;
  top: 50%;
  left: 15%;
}

.radio .cr .cr-icon {
  margin-left: 0.04em;
}

.checkbox label input[type="checkbox"],
.radio label input[type="radio"] {
  display: none;
}

.checkbox label input[type="checkbox"]+.cr>.cr-icon,
.radio label input[type="radio"]+.cr>.cr-icon {
  opacity: 0;
}

.checkbox label input[type="checkbox"]:checked+.cr>.cr-icon,
.radio label input[type="radio"]:checked+.cr>.cr-icon {
  opacity: 1;
}

.checkbox label input[type="checkbox"]:disabled+.cr,
.radio label input[type="radio"]:disabled+.cr {
  opacity: .5;
}

Answer 2

您必须将 Bootstrap 版本 4 与 custom-* 类一起使用才能获得此样式：

 <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta/css/bootstrap.min.css" integrity="sha384-/Y6pD6FV/Vv2HJnA6t+vslU6fwYXjCFtcEpHbNJ0lyAFsXTsjBbfaDjzALeQsN6M" crossorigin="anonymous">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<!-- example code of the bootstrap website -->
<label class="custom-control custom-checkbox">
  <input type="checkbox" class="custom-control-input">
  <span class="custom-control-indicator"></span>
  <span class="custom-control-description">Check this custom checkbox</span>
</label>

<!-- your code with the custom classes of version 4 -->
<div class="checkbox">
  <label class="custom-control custom-checkbox">
    <input type="checkbox" [(ngModel)]="rememberMe" name="rememberme" class="custom-control-input">
    <span class="custom-control-indicator"></span>
    <span class="custom-control-description">Remember me</span>
  </label>
</div>

Bootstrap 版本 3 上的自定义复选框样式？

Bootstrap 版本 3 没有自定义复选框样式，但您可以使用自己的样式。在这种情况下： 如何使用 CSS 设置复选框的样式？

这些自定义样式仅在版本 4 之后可用。
