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?

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。

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

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。

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。

我改变了单选按钮的颜色和大小。试试这个
