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?

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;
}

正如Fred提到的，没有办法在颜色、大小等方面对单选按钮进行本地样式设置。但是您可以使用CSS Pseudo元素来设置任意给定单选按钮的冒名顶替者，并对其进行样式化。谈到JamieD所说的，关于我们如何使用:after Pseudo元素，您可以同时使用:before和:after来实现理想的外观。
这种方法的好处:
Style your radio button and also Include a label for content. Change the outer rim color and/or checked circle to any color you like. Give it a transparent look with modifications to background color property and/or optional use of the opacity property. Scale the size of your radio button. Add various drop shadow properties such as CSS drop shadow inset where needed. Blend this simple CSS/HTML trick into various Grid systems, such as Bootstrap 3.3.6, so it matches the rest of your Bootstrap components visually.
简短演示说明如下:
Set up a relative in-line block for each radio button Hide the native radio button sense there is no way to style it directly. Style and align the label Rebuilding CSS content on the :before Pseudo-element to do 2 things - style the outer rim of the radio button and set element to appear first (left of label content). You can learn basic steps on Pseudo-elements here - http://www.w3schools.com/css/css_pseudo_elements.asp If the radio button is checked, request for label to display CSS content (the styled dot in the radio button) afterwards.
HTML
<div class="radio-item">
<input type="radio" id="ritema" name="ritem" value="ropt1">
<label for="ritema">Option 1</label>
</div>
<div class="radio-item">
<input type="radio" id="ritemb" name="ritem" value="ropt2">
<label for="ritemb">Option 2</label>
</div>
CSS
.radio-item {
display: inline-block;
position: relative;
padding: 0 6px;
margin: 10px 0 0;
}
.radio-item input[type='radio'] {
display: none;
}
.radio-item label {
color: #666;
font-weight: normal;
}
.radio-item label:before {
content: " ";
display: inline-block;
position: relative;
top: 5px;
margin: 0 5px 0 0;
width: 20px;
height: 20px;
border-radius: 11px;
border: 2px solid #004c97;
background-color: transparent;
}
.radio-item input[type=radio]:checked + label:after {
border-radius: 11px;
width: 12px;
height: 12px;
position: absolute;
top: 9px;
left: 10px;
content: " ";
display: block;
background: #004c97;
}
一个简短的演示，看看它的行动
总之，不需要JavaScript，图像或电池。纯CSS。
您可以通过两种纯CSS方式实现自定义单选按钮
Via removing standard appearance using CSS appearance and applying custom appearance. Unfortunately this was doesn't work in IE. Demo: input[type="radio"] { /* remove standard background appearance */ -webkit-appearance: none; -moz-appearance: none; appearance: none; /* create custom radiobutton appearance */ display: inline-block; width: 25px; height: 25px; padding: 6px; /* background-color only for content */ background-clip: content-box; border: 2px solid #bbbbbb; background-color: #e7e6e7; border-radius: 50%; } /* appearance for checked radiobutton */ input[type="radio"]:checked { background-color: #93e026; } /* optional styles, I'm using this for centering radiobuttons */ .flex { display: flex; align-items: center; } <div class="flex"> <input type="radio" name="radio" id="radio1" /> <label for="radio1">RadioButton1</label> </div> <div class="flex"> <input type="radio" name="radio" id="radio2" /> <label for="radio2">RadioButton2</label> </div> <div class="flex"> <input type="radio" name="radio" id="radio3" /> <label for="radio3">RadioButton3</label> </div> Via hiding radiobutton and setting custom radiobutton appearance to label's pseudoselector. By the way no need for absolute positioning here (I see absolute positioning in most demos). Demo: *, *:before, *:after { box-sizing: border-box; } input[type="radio"] { display: none; } input[type="radio"]+label:before { content: ""; /* create custom radiobutton appearance */ display: inline-block; width: 25px; height: 25px; padding: 6px; margin-right: 3px; /* background-color only for content */ background-clip: content-box; border: 2px solid #bbbbbb; background-color: #e7e6e7; border-radius: 50%; } /* appearance for checked radiobutton */ input[type="radio"]:checked + label:before { background-color: #93e026; } /* optional styles, I'm using this for centering radiobuttons */ label { display: flex; align-items: center; } <input type="radio" name="radio" id="radio1" /> <label for="radio1">RadioButton1</label> <input type="radio" name="radio" id="radio2" /> <label for="radio2">RadioButton2</label> <input type="radio" name="radio" id="radio3" /> <label for="radio3">RadioButton3</label>
这对我很有效，
简单添加css属性:
输入(type = "电台"]{强调色:红色;}
这里是资源链接
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;
}
将单选按钮绑定到样式标签可能会有所帮助。进一步的细节在这个回答中。
