如何在css中自定义复选框中更改复选框颜色？

Question

我一直在为复选框中的某些功能工作，但这在更改复选框的样式时让我有点困惑。

我尝试在点击后将颜色设置为复选框，但不起作用。

.container input:checked ~ .checkmark:after {
    display: block;
    color: #000 !important; 
}

这似乎有点容易，但不知何故，方法框颜色（白色）无法更改。有人可以帮助我吗？

这是代码段。

＆＃13;

＆＃13;

.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;
}

/* Hide the browser's default checkbox */
.container input {
    position: absolute;
    opacity: 0;
    cursor: pointer;
}

/* Create a custom checkbox */
.checkmark {
    position: absolute;
    top: 0;
    left: 0;
    height: 25px;
    width: 25px;
    background-color: #eee;
}

/* On mouse-over, add a grey background color */
.container:hover input ~ .checkmark {
    background-color: #ccc;
}

/* When the checkbox is checked, add a blue background */
.container input:checked ~ .checkmark {
    background-color: #2196F3;
}

/* Create the checkmark/indicator (hidden when not checked) */
.checkmark:after {
    content: "";
    position: absolute;
    display: none;
}

/* Show the checkmark when checked */
.container input:checked ~ .checkmark:after {
    display: block;
    color: #000 !important; 
}

/* Style the checkmark/indicator */
.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);
}

＆＃13;

<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">

Answer 1

正在使用边框颜色创建复选标记，此处为：

.container .checkmark:after {
    border: solid white;
}

所以只需根据需要更改颜色：

＆＃13;

＆＃13;

.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;
}

/* Hide the browser's default checkbox */
.container input {
    position: absolute;
    opacity: 0;
    cursor: pointer;
}

/* Create a custom checkbox */
.checkmark {
    position: absolute;
    top: 0;
    left: 0;
    height: 25px;
    width: 25px;
    background-color: #eee;
}

/* On mouse-over, add a grey background color */
.container:hover input ~ .checkmark {
    background-color: #ccc;
}

/* When the checkbox is checked, add a blue background */
.container input:checked ~ .checkmark {
    background-color: #2196F3;
}

/* Create the checkmark/indicator (hidden when not checked) */
.checkmark:after {
    content: "";
    position: absolute;
    display: none;
}

/* Show the checkmark when checked */
.container input:checked ~ .checkmark:after {
    display: block;
}

/* Style the checkmark/indicator */
.container .checkmark:after {
    left: 9px;
    top: 5px;
    width: 5px;
    height: 10px;
    border: solid #000;
    border-width: 0 3px 3px 0;
    -webkit-transform: rotate(45deg);
    -ms-transform: rotate(45deg);
    transform: rotate(45deg);
}

＆＃13;

<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>

如果您尝试更改刻度线的颜色，则必须更改边框颜色。

.container input:checked ~ .checkmark:after {
    display: block;
    border-color: #000; 
}

.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;
}

/* Hide the browser's default checkbox */
.container input {
    position: absolute;
    opacity: 0;
    cursor: pointer;
}

/* Create a custom checkbox */
.checkmark {
    position: absolute;
    top: 0;
    left: 0;
    height: 25px;
    width: 25px;
    background-color: #eee;
}

/* On mouse-over, add a grey background color */
.container:hover input ~ .checkmark {
    background-color: #ccc;
}

/* When the checkbox is checked, add a blue background */
.container input:checked ~ .checkmark {
    background-color: #2196F3;
}

/* Create the checkmark/indicator (hidden when not checked) */
.checkmark:after {
    content: "";
    position: absolute;
    display: none;
}

/* Show the checkmark when checked */
.container input:checked ~ .checkmark:after {
    display: block;
    border-color: #000; 
}

/* Style the checkmark/indicator */
.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>
