基于CSS的复选框样式

Question

我有一个复选框，其外观应如下所示，

如果未选中，则应如下所示，

我有以下CSS

input[type="checkbox"]:checked + label::after {
  content: '';
  position: absolute;
  width: 11px;
  height: 6px;
  background: rgba(0,0,0,0);
  top: 10px;
  left: 24px;
  border: 1px solid white;
  border-top: none;
  border-right: none;
  -webkit-transform: rotate(-45deg);
  -moz-transform: rotate(-45deg);
  -o-transform: rotate(-45deg);
  -ms-transform: rotate(-45deg);
  transform: rotate(-45deg);
}

input[type="checkbox"] {
  line-height: 2.1ex;
}

input[type="radio"],
input[type="checkbox"] {
   position: absolute;
   left: -999em;
}

input[type="checkbox"] + label {
   position: relative;
   overflow: hidden;
   cursor: pointer;
}

input[type="checkbox"] + label::before {
  content: "";
  display: inline-block;
  vertical-align: -25%;
  height: 20px;
  width: 20px;
  background-color: #1BAAD3;
  border-radius: 4px;
  margin-right: 8px;
}

当我取消选中此复选框时，我将看到

我正在使用angular-js处理选择/取消选择事件

HTML

<div class="form-check">
   <input type="checkbox" ng-if="testKits" ng-model="testKits" class="form-check-input" id="testKits">
   <label class="form-check-label form-label-text source-sans-pro" for="testKits">{{'Testkits' | translate}}</label>
</div>

}

input[type="radio"],
