<div class="address-list">
          <div class="address-list-item">
            <label class="radio" for="diyi" class="label">
              <input type="radio" name="address" value="1" id="diyi" style="float:left"><i></i>
              <div>
                <div class="shouhuo-info">汪汪 <span>17523459962</span></div>
                <div class="address-detail">北京市海淀区楼北京市海淀区楼</div>
              </div>
            </label>
          </div>
          <div class="address-list-item">
            <label class="radio" for="disan" class="label">
              <input type="radio" name="address" value="1" id="disan" style="float:left"><i></i>
              <div>
                <div class="shouhuo-info">汪汪 <span>17523459962</span></div>
                <div class="address-detail">北京市1楼北京市海淀区1楼</div>
              </div>
            </label>
          </div>
        </div>

CSS代码：

/* 单选换颜色 */
.radio {
  position: relative;
  display: inline-block;
  font-weight: 400;
  padding-left: 25px;
  text-align: left;
  width: 100%;
  display: flex;
}

.radio input {
  position: absolute;
  left: -9999px;
}

.radio i {
  display: block;
  position: absolute;
  top: 2px;
  left: 2px;
  width: 13px;
  height: 13px;
  outline: 0;
  border: 1px solid rgb(133, 133, 133);
  background: transparent;
  border-radius: 50%;
  transition: border-color .3s;
  -webkit-transition: border-color .3s;
}

.radio input+i:after {
  position: absolute;
  content: '';
  top: 2px;
  left: 2px;
  width: 9px;
  height: 9px;
  border-radius: 50%;
  background-color: #ee2e2e;
