对于那些喜欢从最小示例开始开发的人来说，这里有一个简单的自定义单选按钮，它不依赖于标签:

[type="radio"] { visibility: hidden; /* hide default radio button */ /* you may need to adjust margin here, too */ } [type="radio"]::before { /* create pseudoelement */ border: 2px solid gray; /* thickness, style, color */ height: .9em; /* height adjusts with font */ width: .9em; /* width adjusts with font */ border-radius: 50%; /* make it round */ display: block; /* or flex or inline-block */ content: " "; /* won't display without this */ cursor: pointer; /* appears clickable to mouse users */ visibility: visible; /* reverse the 'hidden' above */ } [type="radio"]:checked::before { /* selected */ /* add middle dot when selected */ /* slightly bigger second value makes it smooth */ /* even more (e.g., 20% 50%) would make it fuzzy */ background: radial-gradient(gray 36%, transparent 38%); } <br> <input type="radio" name="example" id="one" value="one"> <label for="one">one</label> <br> <br> <input type="radio" name="example" id="two" value="two"> <label for="two">two</label>

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。

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;
}

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;
}

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>

    display: inline-block;
    height: 25px;
    line-height: 25px;
    margin: 0;
