我的意思是，单选按钮本身由一个圆形和中心的一个点组成(当按钮被选中时)。我想改变的是两者的颜色。使用CSS可以做到这一点吗?

简单的跨浏览器自定义单选按钮的例子
.checkbox input{ display: none; } .checkbox input:checked + label{ color: #16B67F; } .checkbox input:checked + label i{ background-image: url('http://kuzroman.com/images/jswiddler/radio-button.svg'); } .checkbox label i{ width: 15px; height: 15px; display: inline-block; background: #fff url('http://kuzroman.com/images/jswiddler/circle.svg') no-repeat 50%; background-size: 12px; position: relative; top: 1px; left: -2px; } <div class="checkbox"> <input type="radio" name="sort" value="popularity" id="sort1"> <label for="sort1"> <i></i> <span>first</span> </label> <input type="radio" name="sort" value="price" id="sort2"> <label for="sort2"> <i></i> <span>second</span> </label> </div>

这在本地CSS中是不可能的。您必须使用背景图像和一些javascript技巧。
一个聪明的方法是创建一个单独的div，高度和宽度为-例如- 50px，然后半径为50px，将其放在单选按钮上…
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;
}
来源于如何创建自定义单选按钮
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;
visibility: visible;
width: 20px;
height: 20px;
border-radius: 10px;
border: 2px inset rgba(150,150,150,0.75);
background: radial-gradient(ellipse at top left, rgb(255,255,255) 0%, rgb(250,250,250) 5%, rgb(230,230,230) 95%, rgb(225,225,225) 100%);
content: "";
}
.radio-item input[type=radio]:checked:after {
position: relative;
top: 0;
left: 9px;
display: inline-block;
visibility: visible;
border-radius: 6px;

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

单选按钮是特定于每个操作系统/浏览器的原生元素。没有办法改变它的颜色/风格，除非你想实现自定义图像或使用自定义Javascript库，其中包括图像(例如这个-缓存链接)
