正如其他人所说，没有办法在所有浏览器中实现这一点，所以跨浏览器实现这一点的最好方法是使用javascript。基本上你必须把你的单选按钮变成链接(完全可自定义通过CSS)。每次点击链接都将绑定到相关的单选框，切换他的状态和其他所有状态。

只有当你的目标是基于webkit的浏览器(Chrome和Safari，也许你正在开发Chrome WebApp，谁知道…)，你可以使用以下:

input[type='radio'] {
   -webkit-appearance: none;
}

然后将其设置为一个简单的HTML元素，例如应用背景图像。

使用input[type='radio']:active用于选择输入时，提供备用图形

更新:截至2018年，您可以添加以下内容以支持多个浏览器供应商:

input[type="radio"] {
  -webkit-appearance: none;
  -moz-appearance: none;
  appearance: none;
}

您可以使用css中的重音颜色属性来更改复选框和单选按钮的背景颜色。

input[type=radio] {
  accent-color: red;
}

我构建了@klewis的代码样本的另一个分支，通过使用:before/:after伪元素和隐藏的单选输入按钮来演示纯css和渐变。

HTML:

sample radio buttons:
<div style="background:lightgrey;">
    <span class="radio-item">
        <input type="radio" id="ritema" name="ritem" class="true" value="ropt1" checked="checked">
        <label for="ritema">True</label>
    </span>

    <span class="radio-item">
        <input type="radio" id="ritemb" name="ritem" class="false" value="ropt2">
        <label for="ritemb">False</label>
    </span>
</div>

CSS:

.radio-item input[type='radio'] {
    visibility: hidden;
    width: 20px;
    height: 20px;
    margin: 0 5px 0 5px;
    padding: 0;
}
    .radio-item input[type=radio]:before {
        position: relative;
        margin: 4px -25px -4px 0;
        display: inline-block;

        content: "";
    }
        .radio-item input[type=radio]:checked:after {
            position: relative;
            top: 0;
            left: 9px;
            display: inline-block;

            content: "";

            .radio-item input[type=radio].true:checked:after {

            }
            .radio-item input[type=radio].false:checked:after {
                background: radial-gradient(ellipse at top left, rgb(255,225,200) 0%, rgb(250,200,150) 5%, rgb(200,25,0) 95%, rgb(100,25,0) 100%);
            }
.radio-item label {
    display: inline-block;
    height: 25px;
    line-height: 25px;
    margin: 0;
    padding: 0;
}

我改变了单选按钮的颜色和大小。试试这个

.radio-tile-group { display: flex; flex-wrap: wrap; align-items: center; justify-content: center; } .radio-tile-group .input-container { position: relative; margin: 0.9rem; } .radio-tile-group .input-container .radio-button { opacity: 0; position: absolute; top: 0; left: 0; height: 100%; width: 100%; margin: 0; cursor: pointer; } .radio-tile { border: 1px solid #eea236; } .radio-tile-group .input-container .radio-tile-edit { display: flex; flex-direction: column; align-items: center; justify-content: center; width: 25px; font-size: 12px; border-radius: 5px; padding: 0.2rem; transition: transform 300ms ease; height: 25px; } @media (min-width: 375px) and (max-width: 812px) { .radio-tile-group .input-container .radio-tile { margin-inline: 18px; } } .radio-tile-group .input-container .radio-button:checked+.radio-tile { border: 3px solid #2980b9; font-size: 12px; color: #797979; transform: scale(1.05, 1.05); } .radio-tile-group .input-container .radio-button:checked+.radio-tile .icon svg { fill: white; background-color: #2980b9; } .radio-tile-group .input-container .radio-button:checked+.radio-tile-edit { border: 3px solid black; /* font-size: 12px; */ color: #797979; transform: scale(1.05, 1.05); } <label>Radio button colors:</label> <br> <div class="radio-tile-group"> <div class="input-container"> <label class="radio-tile-label" style="background-color: #b60205;border-radius: 5px;"> <input type="radio" value="#b60205" class= "radio-button uncheckall" name="print_color"> <div class="radio-tile-edit" style="background-color: #b60205;"> </label> </div> </div> <div class="input-container"> <label class="radio-tile-label" style="background-color: #d93f0b; border-radius: 5px;"> <input type="radio" value="#d93f0b" class= "radio-button uncheckall" name="print_color"> <div class="radio-tile-edit" style="background-color: #d93f0b;"> </label> </div> </div> <div class="input-container"> <label class="radio-tile-label" style="background-color: #fbca04; border-radius: 5px;"> <input type="radio" value="#fbca04" class= "radio-button uncheckall" name="print_color"> <div class="radio-tile-edit" style="background-color: #fbca04;"> </label> </div> </div> <div class="input-container"> <label class="radio-tile-label" style="background-color: #0e8a16; border-radius: 5px;"> <input type="radio" value="#0e8a16" class= "radio-button uncheckall" name="print_color"> <div class="radio-tile-edit" style="background-color: #0e8a16;"> </label> </div> </div> <div class="input-container"> <label class="radio-tile-label" style="background-color: #006b75; border-radius: 5px;"> <input type="radio" value="#006b75" class= "radio-button uncheckall" name="print_color"> <div class="radio-tile-edit" style="background-color:#006b75"> </label> </div> </div> <div class="input-container"> <label class="radio-tile-label" style="background-color: #1d76db; border-radius: 5px;"> <input type="radio" value="#1d76db" class= "radio-button uncheckall" name="print_color"> <div class="radio-tile-edit" style="background-color: #1d76db;"> </label> </div> </div> <div class="input-container"> <label class="radio-tile-label" style="background-color: #0052cc; border-radius: 5px;"> <input type="radio" value="#0052cc" class= "radio-button uncheckall" name="print_color"> <div class="radio-tile-edit" style="background-color: #0052cc;"> </label> </div> </div> <div class="input-container"> <label class="radio-tile-label" style="background-color: #757575; border-radius: 5px;"> <input type="radio" value="#757575" class= "radio-button uncheckall" name="print_color"> <div class="radio-tile-edit" style="background-color: #757575;"> </label> </div> </div> </div>

您可以在无线电输入中嵌入span元素，然后在检查无线电输入时选择要呈现的颜色。看看下面这个来自w3schools的例子。

<!DOCTYPE html>
<html>
<style>
/* The container */
.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 radio button */
.container input {
  position: absolute;
  opacity: 0;
  cursor: pointer;
}

/* Create a custom radio button */
.checkmark {
  position: absolute;
  top: 0;
  left: 0;
  height: 25px;
  width: 25px;
  background-color: #eee;
  border-radius: 50%;
}

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

/* When the radio button is checked, add a blue background */
.container input:checked ~ .checkmark {
  background-color: #00a80e;
}

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

/* Show the indicator (dot/circle) when checked */
.container input:checked ~ .checkmark:after {
  display: block;
}

/* Style the indicator (dot/circle) */
.container .checkmark:after {
    top: 9px;
    left: 9px;
    width: 8px;
    height: 8px;
    border-radius: 50%;
    background: white;
}
</style>
<body>

<h1>Custom Radio Buttons</h1>
<label class="container">One
  <input type="radio" checked="checked" name="radio">
  <span class="checkmark"></span>
</label>
<label class="container">Two
  <input type="radio" name="radio">
  <span class="checkmark"></span>
</label>
<label class="container">Three
  <input type="radio" name="radio">
  <span class="checkmark"></span>
</label>
<label class="container">Four
  <input type="radio" name="radio">
  <span class="checkmark"></span>
</label>

</body>

在下面的代码段中改变背景颜色就可以了。

/* When the radio button is checked, add a blue background */
.container input:checked ~ .checkmark {
  background-color: #00a80e;
}
