一个简单的修复方法是使用以下CSS属性。

input[type=radio]:checked{
    background: \*colour*\;
    border-radius: 15px;
    border: 4px solid #dfdfdf;
}

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。

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。

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。
