输入[type = radio]：广播伸出之前

Question

圆角只是从正方形或圆形中伸出，所以如果我给before提供白色背景，则收音机的边缘仍然会稍微可见。

input[type=radio] {
  box-sizing: border-box;
  margin: 0;
  padding: 0;
  position: relative;
  cursor: pointer;
}

input[type=radio]:before {
  content: "";
  display: block;
  width: 16px;
  height: 16px;
  border: 2px solid grey;
  border-radius: 50%;
  /* background-color: white; */
  position: absolute;
  top: 0;
  left: 0;
}

> <input type="radio" name="r" checked>

如何使用CSS before完全隐藏单选按钮？

Answer 1

我认为使用visibility:hidden可能会有所帮助，请检查以下内容：

input[type=radio] {
  box-sizing: border-box;
  margin: 0;
  padding: 0;
  position: relative;
  cursor: pointer;
  visibility: hidden;
 
}

input[type=radio]:before {
  content: "";
  display: block;
  width: 16px;
  height: 16px;
  border: 2px solid grey;
  border-radius: 50%;
  /* background-color: white; */
  position: absolute;
  top: 0;
  left: 0;
  visibility: visible;
  
}
input[type=radio]:checked:after {
    content: "";
    display: block;
    width: 10px;
    height: 10px;
    /* border: 2px solid green; */
    border-radius: 50%;
    background-color: green;
    position: absolute;
    top: 5px;
    left: 5px;
    visibility: visible;
}

<input type="radio" name="r" checked>

在这里，我尝试了另一种方法来添加span。试试看。

.customRadio {
  position: relative;
}
input[type="radio"] {
  opacity: 0;
  margin: 0 5px 0 0;
  transition: all 0.2s ease 0s;
}
input[type="radio"] + .radioSpan {
  background-color: transparent;
  border: 1px solid #aaaaaa;
  border-radius: 50%;
  content: "";
  height: 17px;
  left: 0;
  position: absolute;
  top: 2px;
  width: 17px;
  transition: all 0.3s ease 0s;
}
input[type="radio"]:focus + .radioSpan,
input[type="radio"]:active + .radioSpan {
  box-shadow: 0 3px 5px 0 rgba(56, 49, 132, 0.5) !important;
}
input[type="radio"]:checked + .radioSpan {
  background-color: #408BF9;
  border: 1px solid transparent;
}
input[type="radio"]:checked + .radioSpan::before {
  background-color: #ffffff;
  border-radius: 50%;
  bottom: 0;
  content: "";
  height: 9px;
  left: 0;
  margin: auto;
  position: absolute;
  right: 0;
  top: 0;
  width: 9px;
  z-index: 1;
}
input[type="radio"] ~ .radioText {
  display: inline-block;
  font-family: 'Roboto', sans-serif;
  margin-left: 5px;
  text-transform: capitalize;
}

<label class="customRadio">
    <input type="radio"name="reportType" value="unsigned-report"/>
    <span class="radioSpan"></span>
    <span class="radioText">UnSigned Report</span>
</label>

请找到以下解决方案： HTML：

<div class="radio">
    <input type="radio" name="r" checked>
</div>

CSS：

.radio {
  box-sizing: border-box;
  margin: 0;
  padding: 0;
  position: relative;
  cursor: pointer;
}

.radio::before {
  content: "";
  visibility: hidden; // option-1
  /* opacity: 0;  // option-2 */
  /* display: none; //option-3 */
}
