【HTML+CSS】纯CSS设置checkbox大小和样式 附Radio的去除默认样式和自定义样式

话不多说，直接上效果图：

一、使用的基本div：

<div class="check-item">
    <input type="checkbox" class="check-item-in" id="checkbox3">正常复选框
    <label for="checkbox3"></label>
</div>

<div class="check-item">
    <input type="checkbox" class="check-item-in" id="checkbox1" checked="checked">复选框checked
    <label for="checkbox1"></label>
</div>

<div class="check-item">
    <input type="checkbox" class="check-item-in" id="checkbox2" disabled="true">复选框disableed
    <label for="checkbox2"></label>
</div>

二、自定义样式：

input[type=checkbox] {
    margin-right: 10px;
    cursor: pointer;
    width: 15px;
    height: 15px;
    position: relative;
}

input[type=checkbox]:after {
    position: absolute;
    width: 10px;
    height: 15px;
    top: 0;
    content: " ";
    background-color: #fff;
    color: #fff;
    display: inline-block;
    visibility: visible;
    border: 1px solid grey;
    padding: 0 3px;
    border-radius: 3px;
}

input[type=checkbox]:checked:after {
    background-color: #0f97e7;
    content: "✓";
    font-size: 12px;
}

input[type=checkbox]:disabled:after {
    width: 10px;
    height: 15px;
    top: 0;
    color: #fff;
    display: inline-block;
    visibility: visible;
    border: 1px solid grey;
    padding: 0 3px;
    border-radius: 3px;
    background-color: #E9E7E3;
    content: "✓";
    font-size: 12px;
}

三、另外一种使用图片的：

input[type="checkbox"] {
    display: none;
    -webkit-appearance: none;
    /*去除系统默认appearance的样式,常用于IOS下移除原生样式*/
    margin: 0;
}

.check-item .check-item-in+label {
    width: 22px;
    height: 22px;
    display: inline-block;
    background: #fff url(./checkbox_01.png) no-repeat;
    background-size: contain;
    cursor: pointer;
}

.check-item .check-item-in:checked+label {
    background: #fff url(./checkbox_02.png) no-repeat;
    background-size: contain;
}

.check-item-in:disabled+label {
    background: #fff url(./checkbox_03.png) no-repeat;
    background-size: contain;
}

附：Radio的去除默认样式和自定义样式

input[type = "radio"] {
    appearance: none;
    -webkit-appearance: none;
    outline: none;
    margin: 0;
    vertical-align: text-bottom;
    margin-right: 0.1rem;
}

.checked:after {
    content: "\2713";
    position: absolute;
    left: 62%;
    top: 61%;
    display: block;
    width: 20px;
    height: 20px;
    text-align: center;
    line-height: 20px;
    background: #0555b8;
    color: #fff;
    border: 1px solid #0555b8;
    border-radius: 50%;
    z-index: 99;
    margin: -15px 0 0 -15px;
}

$('input[type="radio"]').click(function () {
    $('[name=' + $(this).attr('name') + ']').each(function () {
        $(this).removeClass('checked');
    });
    $(this).addClass('checked');
});
