一个聪明的方法是创建一个单独的div，高度和宽度为-例如- 50px，然后半径为50px，将其放在单选按钮上…

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。)

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>

您应该使用重音颜色CSS属性，它为用户界面控件(如输入(单选按钮，复选框…)或进度条设置重音颜色，大多数现代浏览器都支持它。

input {
    accent-color: red;
}

document.querySelector("input[name=accent-color]").addEventListener("input", () => { document.documentElement.style.setProperty("--accent-color", event.target.value); }); :root { --accent-color: red; } input, progress { accent-color: var(--accent-color); } /* Other styles */ label { display: flex; align-items: center; gap: .625rem; margin-bottom: .625rem; } label:first-child { font-size: 1.15rem; font-weight: bold; } input { flex: 0 0 auto; height: 1.25rem; width: 1.25rem; } input[type="color"] { width: 3rem; } input[type="range"] { width: 12.5rem; } <label>Change the accent color<input name="accent-color" type="color" value="#ff0000"></input></label><br> <label><input name="radio" type="radio" checked></input>Radio button</label> <label><input name="radio" type="radio"></input>Another radio button</label> <label><input name="check" type="checkbox" checked></input>Checkbox</label> <label><input name="range" type="range"></input>Range input</label> <label><progress value="50" max="100"></progress>Progress bar</label>

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)

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; }
