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>

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)

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;
            width: 12px;
            height: 12px;
            background: radial-gradient(ellipse at top left, rgb(245,255,200) 0%, rgb(225,250,100) 5%, rgb(75,175,0) 95%, rgb(25,100,0) 100%);
            content: "";
        }
            .radio-item input[type=radio].true:checked:after {
                background: radial-gradient(ellipse at top left, rgb(245,255,200) 0%, rgb(225,250,100) 5%, rgb(75,175,0) 95%, rgb(25,100,0) 100%);
            }
            .radio-item input[type=radio].false:checked:after {
                background: radial-gradient(ellipse at top left, rgb(255,225,200) 0%, rgb(250,200,150) 5%, rgb(200,25,0) 95%, rgb(100,25,0) 100%);
            }
.radio-item label {
    display: inline-block;
    height: 25px;
    line-height: 25px;
    margin: 0;
    padding: 0;
}

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>

你可以使用CSS的重音颜色属性来改变颜色。

input[type='radio'] {
    accent-color: #232323;
}

它适用于Chrome/Edge 93+， Firefox 92+和Safari 15.4+(浏览器支持信息来自caniuse。)

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。
