Question

我想知道在点击后如何在我的自定义复选框内进行检查。我试图隐藏我的自定义下面的常规复选框。用户勾选复选框后，如何获得黑色和简单的勾号？

＆＃13;

// Custom Checkbox
.xCheckbox {
  width: 25px;
  margin-left: 40px;
  position: relative;
}


/**
    * The box
    */

.xCheckbox label {
  margin-top: 5px;
  position: absolute;
  cursor: pointer;
  width: 20px;
  height: 20px;
  border-radius: 3px;
  top: 0;
  left: 0;
  background-color: blue;
  border: 1px solid #ddd;
}


/**
    * The tick
    */

.xCheckbox input[type=checkbox]:checked+label {
  transform: rotate(-45deg);
  /* Testing purpose */
}

＆＃13;

<div class="xCheckbox">
  <input type="checkbox" value="1" id="xCheckboxInput" name="" />
  <label for="xCheckboxInput"></label>
</div>

使用label上的伪元素创建勾选并默认隐藏它。选中input后，显示勾号。

此外，要隐藏默认输入框，您可以将其不透明度设置为0：

#customCheckboxInput {
  opacity: 0;
}

// Custom Checkbox
.customCheckbox {
  width: 25px;
  margin-left: 40px;
  position: relative;
}

#customCheckboxInput {
  opacity: 0;
}


/**
 * The box
 */

.customCheckbox label {
  margin-top: 5px;
  position: absolute;
  cursor: pointer;
  width: 20px;
  height: 20px;
  border-radius: 3px;
  top: 0;
  left: 0;
  background-color: blue;
  border: 1px solid black;
}


/**
 * The tick
 */

.customCheckbox input[type=checkbox]+label::after {
  content: "\2713";
  color: #000;
  text-align: center;
  opacity: 0;
  position: absolute;
  left: 2px;
  transform: rotate(45deg);
  font-weight: bold;
}

.customCheckbox input[type=checkbox]:checked+label {
  transform: rotate(-45deg);
  /* Testing purpose */
  cursor: pointer;
  /* doesnt work like supposed to */
}

.customCheckbox input[type=checkbox]:checked+label::after {
  opacity: 1;
}

<div class="customCheckbox">
  <input type="checkbox" value="1" id="customCheckboxInput" name="" />
  <label for="customCheckboxInput"></label>
</div>

根据要求，要使用多个复选框创建此效果，需要重新处理HTML和CSS。

基本上......将input和label包装在容器div中。这解决了position: absolute重叠标签的问题。

我试图在这个例子中简化初始CSS，最值得注意的是完全从伪元素创建自定义复选框，而不是标签的样式。为简单起见，从演示中删除了转换属性。
