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>

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。

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;
}

如果你使用react bootstrap Form。你可以这样做

HTML

<Form.Check
type="radio"
id="Radio-card"
label={`check me out`}
name="paymentmethod"
value="card"
/>

SCSS

.form-check {
    display: flex;
    align-items: center;
    input[type="radio"] {
    -moz-appearance: none;
    appearance: none;
          
    width: 11px;
    height: 11px;
    padding: 1px;
    background-clip: content-box;
    border: 1px solid hotpink;
    background-color: white;
    border-radius: 50%;
    }
          
    input[type="radio"]:checked {
    outline: none;
    background-color: hotpink;
    border: 1px solid hotpink;
    }
    label {
    font-size: 14px;
    font-weight: 600;
    }
}

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; }
