简单的方法是使用重音色

CSS属性的作用是:为某些元素生成的用户界面控件设置强调色

支持重音颜色的浏览器目前将其应用于以下HTML元素:

<input type="checkbox">
<input type="radio">
<input type="range">
<progress>

一个可运行的示例

body { display: grid; padding: 3rem 0; } .accent { accent-color: #30cc7e; } form { display: grid; grid-auto-columns: fit-content(50%); grid-template-areas: "a a"; margin: auto; padding: 0; gap: 1rem; } form { display: grid; grid-template-columns: 1fr 1fr; gap: 2rem; margin: auto; } form section:first-child { color-scheme: light; } form section:last-child { color-scheme: dark; } fieldset { border-radius: 8px; color-scheme: light; display: flex; flex: 1; flex-direction: column; gap: 1rem; padding: 1rem; } .dark { color-scheme: dark; } .dark fieldset { background: #100f33; border-color: #100f33; color: #fff; } .dark .accent { accent-color: hsla(180, 100%, 70%, 1); } h2 { margin: 0; } .notice { background: #fff9c4; border-radius: 6px; margin: 1.5rem auto; padding: 0.5rem; text-align: center; } @supports (accent-color: #fff) { .notice { display: none; } } <div class="notice"> Your browser does not support the <code>accent-color</code> property. </div> <form action=""> <fieldset> <h2>Checkboxes</h2> <div> <label for="checkbox"> Default </label> <input id="checkbox" type="checkbox" checked> </div> <div> <label for="checkbox-accent"> Accent </label> <input id="checkbox-accent" type="checkbox" class="accent" checked> </div> </fieldset> <fieldset> <h2>Radio</h2> <div> <input id="radio" type="radio" checked> <label for="radio"> Default </label> </div> <div> <input id="radio-accent" type="radio" class="accent" checked> <label for="radio-accent"> Accent </label> </div> </fieldset> <fieldset> <h2>Progress</h2> <div> <label for="progress"> Default </label> <progress id="progress" min="0" max="100" value="50"></progress> </div> <div> <label for="progress-accent"> Accent </label> <progress id="progress-accent" class="accent" min="0" max="100" value="50"></progress> </div> </fieldset> <fieldset> <h2>Range</h2> <div> <label for="range"> Default </label> <input id="range" type="range"> </div> <div> <label for="range-accent"> Accent </label> <input id="range-accent" class="accent" type="range"> </div> </fieldset> </form>

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; }

`

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。

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>
