  • 复选框、单选框的自定义样式

    ---恢复内容开始---

      在很多时候,浏览器自带的单选框和复选框的样式不够美观,并且浏览器的样式之间带有差异。已经不足以我们生产的需求。下面用css来自定义修改一下单选框与复选框的样式。

      首先我们先看一下例子的效果:

      

      上图是我这边例子的效果图,最后会将整个代码贴在最后,以供参考。

    • 复选框自定义样式

      复选框我们最经常遇到的问题,就是对号的样式多种多样,或者颜色多种。

      这边自定义复选框样式的逻辑方法是:清楚复选框原来的样式,重新定义input的样式以及选中情况下的样式,对号可以使用图片填充。

      复选框html内容如下:

    <input type="checkbox" id="checkbox1"><label for="checkbox1">123</label>
    <input type="checkbox" id="checkbox2"><label for="checkbox2">23</label>

      上面复选框的样式如下:

    input[type="checkbox"] {
       20px;
      height: 20px;
      background-color: #fff;
      -webkit-appearance: none;
      border: 1px solid #c9c9c9;
      border-radius: 2px;
      outline: none;
    }
    input[type="checkbox"]:checked {
      background: url("https://gss1.bdstatic.com/9vo3dSag_xI4khGkpoWK1HF6hhy/baike/c0%3Dbaike92%2C5%2C5%2C92%2C30/sign=5bc58607708b4710da22f59ea2a7a898/622762d0f703918f418843ec533d269759eec4bf.jpg")
        no-repeat center;
      background-size: 100% 100%;
    }
    

      这里使用属性选择器选中复选框,appearance:none清除默认样式后重新设置样式。复选框被选中后使用图片填充。

    • 单选框自定义样式

      单选框自定义逻辑方法:清除radio的默认样式,使用伪元素模拟单选框样式。

      性别例子html内容如下:

    <p>您的性别:</p>
        <div class="radio-sex">
            <input type="radio" id="sex1" name="sex">
            <label for="sex1"></label>
            <span>男</span>
        </div>
        <div class="radio-sex">
            <input type="radio" id="sex2" name="sex">
            <label for="sex2"></label>女
        </div>
    

      css内容如下:

    .radio-sex {
      position: relative;
      display: inline-block;
      margin-right: 12px;
    }
    
    .radio-sex input {
      vertical-align: middle;
      /* 前面三行代码是为了让radio单选按钮与文字对齐 */
       20px;
      height: 20px;
      appearance: none; /*清楚默认样式*/
      -webkit-appearance: none;
      opacity: 0;
      outline: none;
      /* 注意不能设置为display:none*/
    }
    
    .radio-sex label {
      position: absolute;
      left: 0;
      top: 0;
      z-index: 1;
      /*注意层级关系,如果不把label层级设为最低,会遮挡住input而不能单选*/
       20px;
      height: 20px;
      border: 1px solid #3582e9;
      border-radius: 100%;
    }
    
    .radio-sex input[type="radio"]:checked + label {
      background: #3582e9;
    }
    
    .radio-sex input[type="radio"]:checked + label::after {
      content: "";
      position: absolute;
      left: 7px;
      top: 2px;
       5px;
      height: 12px;
      border-right: 1px solid #fff;
      border-bottom: 1px solid #fff;
      transform: rotate(45deg);
    }
    .radio-sex span{
        vertical-align: middle;
    }
    

      单选框选中样式使用属性选择器、:checked选择器、相邻兄弟选择器和伪元素完成。当被选中时,对号通过设置右边框和下边框通过旋转45度实现效果。

      其他关于颜色和数字的单选框样式和上边的例子差不多。

      数字例子里面右下角的小对号是我通过引入阿里矢量库里面的icon实现的。

      下面贴上整个代码以供参考:

    <template>
        <div class="main">
            <div class="div">123</div>

            <input type="checkbox" id="checkbox2"><label for="checkbox2">23</label>
        <p>您的性别:</p>
        <div class="radio-sex">
            <input type="radio" id="sex1" name="sex">

            <span>男</span>
        </div>
        <div class="radio-sex">
            <input type="radio" id="sex2" name="sex">

        <p>喜欢的颜色:</p>

    .radio-check input[type="radio"] {
      opacity: 0;
    }
    .radio-check label {
      display: inline-block;
      /* min- 50px; */
      height: 24px;
      line-height: 24px;
      text-align: center;
      padding-right: 10px;
      border: 1px solid #c9c9c9;
      border-radius: 5px;
      padding-left: 10px;
      cursor: pointer;
    }
    .radio-check input[type="radio"]:checked + label + span {
      color: #3597db;
      opacity: 1;
    }
    .radio-check input[type="radio"]:checked + label {
      border-color: #3597db;
    }
    .radio-check input[type="radio"]:hover + label {
      border-color: #3597db;
    }
    </style>
    

      当然也还是有其他办法,通过动态绑定class也可以模拟单选框选中的样式。

      以上代码以测试成功,欢迎留言。
