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)

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>

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);
        background: radial-gradient(ellipse at top left, rgb(255,255,255) 0%, rgb(250,250,250) 5%, rgb(230,230,230) 95%, rgb(225,225,225) 100%);
        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;
}

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;
}

试试这个带有过渡的css:

Demo

$DarkBrown: #292321;

$Orange: #CC3300;

div {
  margin:0 0 0.75em 0;
}

input[type="radio"] {
    display:none;
}
input[type="radio"] + label {
    color: $DarkBrown;
    font-family:Arial, sans-serif;
    font-size:14px;
}
input[type="radio"] + label span {
    display:inline-block;
    width:19px;
    height:19px;
    margin:-1px 4px 0 0;
    vertical-align:middle;
    cursor:pointer;
    -moz-border-radius:  50%;
    border-radius:  50%;
}

input[type="radio"] + label span {
     background-color:$DarkBrown;
}

input[type="radio"]:checked + label span{
     background-color:$Orange;
}

input[type="radio"] + label span,
input[type="radio"]:checked + label span {
  -webkit-transition:background-color 0.4s linear;
  -o-transition:background-color 0.4s linear;
  -moz-transition:background-color 0.4s linear;
  transition:background-color 0.4s linear;
}

Html:

<div>
  <input type="radio" id="radio01" name="radio" />
  <label for="radio01"><span></span>Radio Button 1</label>
</div>

<div>
 <input type="radio" id="radio02" name="radio" />
 <label for="radio02"><span></span>Radio Button 2</label>
</div>

为了创建额外的元素，我们可以使用:after，:before(所以我们不需要对HTML进行太多的更改)。对于单选按钮和复选框，我们可以使用:checked。我们还可以使用其他一些伪元素(例如:hover)。使用这些组合，我们可以创建一些非常酷的自定义表单。检查这个
