选中时尝试更改自定义复选框标签的颜色，仅 CSS [重复]

Question

我可以更改复选框的颜色，但我似乎无法更改文本标签的颜色。我想用 CSS 做到这一点。这是我的代码。

.container {
  display: block;
  position: relative;
  padding-left: 35px;
  margin-bottom: 12px;
  cursor: pointer;
  font-size: 22px;
  -webkit-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  user-select: none;
}

.container input {
  position: absolute;
  opacity: 0;
  cursor: pointer;
}

.checkmark {
  position: absolute;
  top: 0;
  left: 0;
  height: 25px;
  width: 25px;
  background-color: #eee;
}

.container:hover input~.checkmark {
  background-color: #ccc;
}

.container+label input:checked~.checkmark {
  background-color: #2196F3;
  color: blue;
}

.checkmark:after {
  content: "";
  position: absolute;
  display: none;
}

.container input:checked~.checkmark:after {
  display: block;
}

.container .checkmark:after {
  left: 9px;
  top: 5px;
  width: 5px;
  height: 10px;
  border: solid white;
  border-width: 0 3px 3px 0;
  -webkit-transform: rotate(45deg);
  -ms-transform: rotate(45deg);
  transform: rotate(45deg);
}

<label class="container">One
      <input type="checkbox" checked="checked">
      <span class="checkmark"></span>
    </label>
<label class="container">Two
      <input type="checkbox">
      <span class="checkmark"></span>
    </label>
<label class="container">Three
      <input type="checkbox">
      <span class="checkmark"></span>
    </label>
<label class="container">Four
      <input type="checkbox">
      <span class="checkmark"></span>
    </label>

我尝试像在许多其他网站上提到的那样使用复选框添加标签选择器，但它不起作用..

非常感谢您的帮助，我为此花费了很多时间，如果能找到解决方案，我会很欣慰的。提前致谢！！

添加以下 css 规则，这应该会改变颜色：

label.container {
    color: #7cbb7c;
}

更新

像这样更改复选框的 html：

<label class="container">
  <input type="checkbox" checked="checked">
  <span class="label">One</span>
  <span class="checkmark"></span>
</label>

添加以下css规则：

input:checked ~ span.label {
   color: #ff00ff;
}

示例

.container {
  display: block;
  position: relative;
  padding-left: 35px;
  margin-bottom: 12px;
  cursor: pointer;
  font-size: 22px;
  -webkit-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  user-select: none;
}

.container input {
  position: absolute;
  opacity: 0;
  cursor: pointer;
}

.checkmark {
  position: absolute;
  top: 0;
  left: 0;
  height: 25px;
  width: 25px;
  background-color: #eee;
}

.container:hover input~.checkmark {
  background-color: #ccc;
}

.container input:checked~.checkmark {
  background-color: #2196F3;
}

/* Add the following css rule: */
.container input:checked~span.label {
  color: #ff00ff;
}

.checkmark:after {
  content: "";
  position: absolute;
  display: none;
}

.container input:checked~.checkmark:after {
  display: block;
}

.container .checkmark:after {
  left: 9px;
  top: 5px;
  width: 5px;
  height: 10px;
  border: solid white;
  border-width: 0 3px 3px 0;
  -webkit-transform: rotate(45deg);
  -ms-transform: rotate(45deg);
  transform: rotate(45deg);
}

<label class="container">
  <input type="checkbox" checked="checked">
  <span class="label">One</span>
  <span class="checkmark"></span>
</label>

<label class="container">
  <input type="checkbox">
  <span class="label">Two</span>
  <span class="checkmark"></span>
</label>
<label class="container">
  <input type="checkbox">
  <span class="label">Three</span>
  <span class="checkmark"></span>
</label>
<label class="container">
  <input type="checkbox">
  <span class="label">Four</span>
  <span class="checkmark"></span>
</label>

Answer 2

下一个选择器+

选择紧跟在第一个指定元素之后（而不是内部）的元素。

使用span 包装标签文本并将其移动到.checkmark

<label class="container">
      <input type="checkbox" checked>
      <span class="checkmark"></span>
      <span class="label"> text</span>
</label>

现在您可以像这样选择它：

input:checked~.checkmark + .label

示例

.container {
  display: block;
  position: relative;
  padding-left: 35px;
  margin-bottom: 12px;
  cursor: pointer;
  font-size: 22px;
  -webkit-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  user-select: none;
}

.container input {
  position: absolute;
  opacity: 0;
  cursor: pointer;
}

.checkmark {
  position: absolute;
  top: 0;
  left: 0;
  height: 25px;
  width: 25px;
  background-color: #eee;
}

.container:hover input~.checkmark {
  background-color: #ccc;
}

.container input:checked~.checkmark {
  background-color: #2196F3;
}


/* Add the following css rule: */

.container input:checked~.checkmark+.label {
  color: #2196F3;
}

.checkmark:after {
  content: "";
  position: absolute;
  display: none;
}

.container input:checked~.checkmark:after {
  display: block;
}

.container .checkmark:after {
  left: 9px;
  top: 5px;
  width: 5px;
  height: 10px;
  border: solid white;
  border-width: 0 3px 3px 0;
  -webkit-transform: rotate(45deg);
  -ms-transform: rotate(45deg);
  transform: rotate(45deg);
}

<label class="container">
      <input type="checkbox" checked>
      <span class="checkmark"></span>
      <span class="label"> First</span>
    </label>

<label class="container">
      <input type="checkbox">
      <span class="checkmark"></span>
      <span class="label"> Second</span>
    </label>

<label class="container">
      <input type="checkbox">
      <span class="checkmark"></span>
      <span class="label"> Third</span>
    </label>
