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>

将单选按钮绑定到样式标签可能会有所帮助。进一步的细节在这个回答中。

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;
}

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。

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 {

            }
.radio-item label {
    display: inline-block;
    height: 25px;
    line-height: 25px;
    margin: 0;
    padding: 0;
}

我改变了单选按钮的颜色和大小。试试这个

.radio-tile-group { display: flex; flex-wrap: wrap; align-items: center; justify-content: center; } .radio-tile-group .input-container { position: relative; margin: 0.9rem; } .radio-tile-group .input-container .radio-button { opacity: 0; position: absolute; top: 0; left: 0; height: 100%; width: 100%; margin: 0; cursor: pointer; } .radio-tile { border: 1px solid #eea236; } .radio-tile-group .input-container .radio-tile-edit { display: flex; flex-direction: column; align-items: center; justify-content: center; width: 25px; font-size: 12px; border-radius: 5px; padding: 0.2rem; transition: transform 300ms ease; height: 25px; } @media (min-width: 375px) and (max-width: 812px) { .radio-tile-group .input-container .radio-tile { margin-inline: 18px; } } .radio-tile-group .input-container .radio-button:checked+.radio-tile { border: 3px solid #2980b9; font-size: 12px; color: #797979; transform: scale(1.05, 1.05); } .radio-tile-group .input-container .radio-button:checked+.radio-tile .icon svg { fill: white; background-color: #2980b9; } .radio-tile-group .input-container .radio-button:checked+.radio-tile-edit { border: 3px solid black; /* font-size: 12px; */ color: #797979; transform: scale(1.05, 1.05); } <label>Radio button colors:</label> <br> <div class="radio-tile-group"> <div class="input-container"> <label class="radio-tile-label" style="background-color: #b60205;border-radius: 5px;"> <input type="radio" value="#b60205" class= "radio-button uncheckall" name="print_color"> <div class="radio-tile-edit" style="background-color: #b60205;"> </label> </div> </div> <div class="input-container"> <label class="radio-tile-label" style="background-color: #d93f0b; border-radius: 5px;"> <input type="radio" value="#d93f0b" class= "radio-button uncheckall" name="print_color"> <div class="radio-tile-edit" style="background-color: #d93f0b;"> </label> </div> </div> <div class="input-container"> <label class="radio-tile-label" style="background-color: #fbca04; border-radius: 5px;"> <input type="radio" value="#fbca04" class= "radio-button uncheckall" name="print_color"> <div class="radio-tile-edit" style="background-color: #fbca04;"> </label> </div> </div> <div class="input-container"> <label class="radio-tile-label" style="background-color: #0e8a16; border-radius: 5px;"> <input type="radio" value="#0e8a16" class= "radio-button uncheckall" name="print_color"> <div class="radio-tile-edit" style="background-color: #0e8a16;"> </label> </div> </div> <div class="input-container"> <label class="radio-tile-label" style="background-color: #006b75; border-radius: 5px;"> <input type="radio" value="#006b75" class= "radio-button uncheckall" name="print_color"> <div class="radio-tile-edit" style="background-color:#006b75"> </label> </div> </div> <div class="input-container"> <label class="radio-tile-label" style="background-color: #1d76db; border-radius: 5px;"> <input type="radio" value="#1d76db" class= "radio-button uncheckall" name="print_color"> <div class="radio-tile-edit" style="background-color: #1d76db;"> </label> </div> </div> <div class="input-container"> <label class="radio-tile-label" style="background-color: #0052cc; border-radius: 5px;"> <input type="radio" value="#0052cc" class= "radio-button uncheckall" name="print_color"> <div class="radio-tile-edit" style="background-color: #0052cc;"> </label> </div> </div> <div class="input-container"> <label class="radio-tile-label" style="background-color: #757575; border-radius: 5px;"> <input type="radio" value="#757575" class= "radio-button uncheckall" name="print_color"> <div class="radio-tile-edit" style="background-color: #757575;"> </label> </div> </div> </div>
