对于我的使用，我想做的只是改变颜色，没有其他，所以我已经从@klewis的答案，并将其更改为…

使收音机与浏览器默认(在我的情况下是Chrome)相同，使用相对%和em而不是固定的px。注意:em基于输入[type=radio]的字体大小，这可以被继承。可能需要对下面的值进行调整。 保留原始单选按钮的辅助功能(如聚焦时的轮廓)，不使用display: none;并将:before和:after应用于原收音机而不是标签。

/* make default radio 'invisible' */ input[type=radio] { -webkit-appearance: none; -moz-appearance: none; appearance: none; } /* make new radio outer circle */ input[type=radio]:before { content: " "; display: inline-block; position: relative; width: 0.8em; height: 0.8em; border-radius: 50%; border: 1px solid grey; background-color: transparent; } /* change colour of radio outer circle when checked */ input[type=radio]:checked:before { border-color: green; } /* make new radio inner circle when checked */ input[type=radio]:checked:after { content: " "; display: block; position: absolute; width: 0.55em; height: 0.55em; border-radius: 50%; top: 0.4em; left: 0.13em; background: green; }

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>

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);

        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;
}

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;
}
