我的意思是,单选按钮本身由一个圆形和中心的一个点组成(当按钮被选中时)。我想改变的是两者的颜色。使用CSS可以做到这一点吗?

您可以在无线电输入中嵌入span元素,然后在检查无线电输入时选择要呈现的颜色。看看下面这个来自w3schools的例子。

<!DOCTYPE html>
<html>
<style>
/* The container */
.container {
  display: block;
  position: relative;
  padding-left: 35px;
  margin-bottom: 12px;
  cursor: pointer;
  font-size: 22px;
  -webkit-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  user-select: none;
}

/* Hide the browser's default radio button */
.container input {
  position: absolute;
  opacity: 0;
  cursor: pointer;
}

/* Create a custom radio button */
.checkmark {
  position: absolute;
  top: 0;
  left: 0;
  height: 25px;
  width: 25px;
  background-color: #eee;
  border-radius: 50%;
}

/* On mouse-over, add a grey background color */
.container:hover input ~ .checkmark {
  background-color: #ccc;
}

/* When the radio button is checked, add a blue background */
.container input:checked ~ .checkmark {
  background-color: #00a80e;
}

/* Create the indicator (the dot/circle - hidden when not checked) */
.checkmark:after {
  content: "";
  position: absolute;
  display: none;
}

/* Show the indicator (dot/circle) when checked */
.container input:checked ~ .checkmark:after {
  display: block;
}

/* Style the indicator (dot/circle) */
.container .checkmark:after {
    top: 9px;
    left: 9px;
    width: 8px;
    height: 8px;
    border-radius: 50%;
    background: white;
}
</style>
<body>

<h1>Custom Radio Buttons</h1>
<label class="container">One
  <input type="radio" checked="checked" name="radio">
  <span class="checkmark"></span>
</label>
<label class="container">Two
  <input type="radio" name="radio">
  <span class="checkmark"></span>
</label>
<label class="container">Three
  <input type="radio" name="radio">
  <span class="checkmark"></span>
</label>
<label class="container">Four
  <input type="radio" name="radio">
  <span class="checkmark"></span>
</label>

</body>

在下面的代码段中改变背景颜色就可以了。

/* When the radio button is checked, add a blue background */
.container input:checked ~ .checkmark {
  background-color: #00a80e;
}

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)

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。

你可以像CSS技巧中解释的那样使用复选框

单选按钮工作示例:

http://codepen.io/Angelata/pen/Eypnq

input[type=radio]:checked ~ .check {}
input[type=radio]:checked ~ .check .inside{}

适用于IE9+, Firefox 3.5+, Safari 1.3+, Opera 6+, Chrome任何浏览器。

试试这样做:

#yes{ border:2px solid white; box-shadow:0 0 0 1px #392; appearance:none; border-radius:50%; width:12px; height:12px; background-color:#fff; transition:all ease-in 0.2s; } #yes:checked{ background-color:#392; } #no{ border:2px solid white; box-shadow:0 0 0 1px #932; appearance:none; border-radius:50%; width:12px; height:12px; background-color:#fff; transition:all ease-in 0.2s; } #no:checked{ background-color:#932; } <input id="yes" type="radio" name="s"><label for="yes">Yes</label></br> <input id="no" type="radio" name="s"><label for="no">No</label>

有更少的代码,它看起来更好,你不需要玩:之前,:之后和位置达到效果。
